LANGUAGE ECOLOGY
Tove Skutnabb-Kangas & Robert Phillipson
1. Introduction
Language plus ecology = language ecology, linguistic ecology, ecolinguistics? Simple? No. The
first serious sociolinguistic attempts to explore linguistic ecology pleaded for linguistics to be
grounded in societal context and change. Trim 1959 and Haugen’s seminal 1971 article entail
multidisciplinarity and build on multilingual scholarship (of the works cited by Trim, eight are
in German, six in English, and four in French; academia has become more monolingual inglobalization processes). Haugen refers to status, standardization, diglossia, and glottopolitics,
but not to language rights (the concept did not exist then – see the entry Language Rights).
Today’s interpretations of what language ecology is range widely. Many researchers use“ecology” simply as a reference to “context” or “language environment”, to describe languagerelated issues embedded in (micro or macro) sociolinguistic, educational, economic or politicalsettings rather than de-contextualised. Here “ecology” has often become a fashionable term for
simply situating language or language study in some way, i.e. it is a metaphor.
Others have more specific definitions and sub-categories (e.g. articles in Fill &Mühlhäusler, 2001; Mufwene, 2001; Mühlhäusler, 1996, 2003; and two pioneers Jørgen Chr.
Bang & Jørgen Døør, see http://www.jcbang.dk/main/ecolinguistics/index.php). In this article,
we use Wendel’s 2005: 51) definition: “The ecological approach to language considers thecomplex web of relationships that exist between the environment, languages, and theirspeakers”. “Environment” here means the physical, biological AND social environments. Manysociolinguists pay only lip-service to the first two.
We start with a discussion of definitions, first language-related, then ecology-related, andfinally put the two together. The connecting concept for us is diversity, and the struggle for its
maintenance, in nature AND culture.
2. Diversities – definitions, status and threats
2.1. Linguistic diversity
The term language is extremely imprecise. For defining what “language” is for our purposes
analysis must engage with those power relations which are decisive for whose definitions about
the relative languageness or otherwise of various idioms prevail and why (see SkutnabbKangas 2000, Chapter 1, for a discussion of what a language is; see also the entry Dialect).
Borders of a concept are often in the perceptions of the observer rather than in thecharacteristics of the observed: languages are, above all, protean. One example of the porous
borders is the 15th edition of the Ethnologue (http://www.sil.org/ethnologue/), the mostcomprehensive global source list for (mostly oral) languages, edited by Raymond G. Gordon,
Jr. of the Summer Institute of Linguistics. It lists 6,912 languages, but some 41,000 names orlabels for various languages.
Even if we knew what a language is, we certainly have extremely unreliable figures for thenumber of speakers for most of them, including the largest ones, where the differences of
estimates of the speakers of the same language may be tens of millions (see Skutnabb-Kangas,
2000).
Languages are in most cases both known best and transmitted to thenext generation by native speakers/usersi or mother tongueii
speakers/users of those languages. But we are likewise using contested
concepts here. Distinguishing mother tongue speakers or native speakers
from those who have learned some language only later and for whom it isnot their primary means of communication in childhood (or one of them,in case of childhood bilinguals or multilinguals) is extremely tricky.
If we could define language and native speaker, we might thenmeasure reliably the relative linguistic diversity of geographical units,
for instance countries, through the number of languages spoken natively
in the country. The most linguistically diverse countries would then be theones with most languages. Papua New Guinea, with its over 850
languages would be the uncontested world champion.
But this way of measuring linguistic megadiversity has also been
contested. Clinton Robinson argues that the most diverse country is not
the one with the largest number of languages, but the one where thelargest linguistic group represents the lowest percentage of all linguistic
groups (Robinson, 1993). There is a very big difference in the list of theworld's linguistically most diverse countries, depending on which of thesemeasures we use – except for the first, Papua New Guinea, on both lists.
Measuring cultural diversity is even more difficult, regardless of how"culture" or "cultural traits" are defined (see, e.g., articles in Posey, ed.,
1999, and Maffi, ed, 2001, for a sampling). Biolinguistic diversity is amore narrow concept than biocultural diversity; language is included inculture.
Equating language groups with cultural groups is even more risky,since there are many examples of non-convergence both ways: several
cultural groups using the same language, or one cultural group using twoor three different languages. When ethnicity, another contested concept,
is added, so that we get ethnocultural groups defined on the basis oflanguages, the measures become even more fluid.
All the concepts used, language and mother tongue, culture, andethnicity, are relational, not characteristics of people; they are social
constructs, not inherited givens; they are hybrid and nomadic, dynamic
and changing, not static; people may claim several of them at the sametime and be multilingual and multicultural, and multiethnic, or"bicountrial". All of them play ever-changing roles for people's multiple
identities, and are variously focussed and emphasized in various
situations and at various times; their salience is always variable. ALL
identities are of course constructed to the extent that we are not bornwith identity genes. Even in cases where we are talking about
phenotypically visible genotypical features like skin colour, very obviously
the way these features are interpreted are social constructions, notinnate.
But with all these caveats and challenges, it is still the case thatmany of those groups who demand linguistic human rights (see the entry
Language rights) do claim these concepts: they claim to know what theirmother tongues are and which ethnic or ethnolinguistic or ethnoculturalgroup(s) they belong to. They see their language as a "cultural corevalue" (Smolicz, 1979). And there is in reality a very high degree of
convergence between ethnicity, culture and mother tongue, regardless of
how much liberal political scientists or post-post-modern sociolinguists
want to denounce this, and "disinvent" the concepts. It seems that thesame few examples of non-convergence and of loss of language, with theculture and identity still living on (the Irish, the Jews, and a few more) areoften repeated and used as proof when claiming that there is little or no
relationship between language and culture. Several of the critics seem,
erroneously to assume that if a concept (such as "mother tongue","language", "ethnicity", "culture") is socially "constructed" (rather than"innate" or "inherited" or "primordial" or whatever one sees as the
opposite of constructed) it is somehow a less valid concept.
Bearing in mind the intrinsic pitfalls in identifying and quantifying
languages, some basics follow about linguistic diversity. There are probably
between 6,500 and 10,000 spoken (oral) languages in the world, andpossibly an equal number of sign languages. Europe and the Middle
East together account for only 4% of the world's oral languages (275according to Krauss 1992: 5). Of the 225 in Europe, 94 are “endangered”(see below). The Americas (North, South and Central) together account foraround 1,000 of the world's oral languages, 15%. The rest, 81% of theworld's oral languages, are in Africa, Asia (around 30% each) and thePacific (just under 20%).
Nine countries in the world have more than 200 languages each,accounting for more than half the world's languages, a total of 3,490(Krauss 1992: 6). Another 13 countries have more than 100 languages
each. These top 22 countries, just over 10 percent of the world's countries,
probably account for some 75 percent (over 5,000) of the world's oral
languages.
The top 10 oral languages in the world, in terms of number of mothertongue speakers (more than 100 million speakers), (Mandarin) Chinese,
Hindi, Spanish, English, Bengali, Portuguese, Arabic, Russian, Japanese andGerman – see Skutnabb-Kangas, Maffi & Harmon, 2003 - represent only
0.10 - 0.15% of the world's oral languages, but account for around half of
the world's oral population. There are around 60 languages with morethan 10 million speakers, together accounting for far over 4 billion
people. Less than 300 languages are spoken by communities of 1 million
speakers and above. Most languages are spoken by fairly few people.
Over half of the world's (oral) and most of the Sign languages are spoken
by communities of less than 10,000 speakers. And half of these, around aquarter of the world's languages, are spoken by communities of 1,000
speakers or less; around 10% of the world's languages are spoken by lessthan 100 speakers each. The median number of speakers of oral
languages is probably some 5-6,000 people.
Languages are today being killediii at a much faster pace than everbefore in human history. As a consequence, linguistic diversity isdisappearing.
2.2. Biological/ecological diversity
Just as the number of languages has been used as a proxy for linguistic
diversity, the number of species has been used as a proxy for biodiversity.
But we have very little solid knowledge of these numbers, much less thanabout the number of languages. Figures of between 5-15 million separate
species are "considered reasonable" (Harmon, 2001: 63), with a "working
figure" of about 12.5 million. But figures as low as 2 million and as high as
50 million (Maffi, 2001, Note 1) or even 100 million (Solé et al., 2003: 26)
have been mentioned. The highest figures are based on the estimate thatmost of the world's species (maybe up to 90%, Mishler, 2001: 71) have
not yet been "discovered", i.e. named and described by (mostly Western)scientists; only some 1.5 million different species (from plants andanimals to fungi, algae, bacteria and viruses) have so far been identified
by natural scientists. Many may become extinct before having beenstudied at all.
A relatively simple global measure of ecological diversity whichcorresponds to a linguistic megadiversity list is megadiversity
countries, Russell & Cristina Mittermeier’s (see 1997) concept (seewww.af-info.or.jp/eng/honor/essays/1997_2.html). These are "countries
likely to contain the highest percentage of the global species richness"(Skutnabb-Kangas, Maffi & Harmon, 2003; see also Conservation
International at
http://www.conservation.org/xp/CIWEB/publications/videos/index.xml).
Researchers have also developed concepts covering larger units where
there is a high concentration of species. Ecoregions and biodiversity
hotspots are important examples.
The World Wide Fund for Nature (WWF) defines an ecoregion as follows:“A relatively large unit of land or water containing a geographicallydistinct assemblage of species, natural communities, and environmental
conditions” (here from Oviedo & Maffi, 2000: 1). The definition mightseem fairly vague, but this is a necessary result of trying to capture thefact that for conservation work (and in general too) species and theirliving conditions have to be seen not as isolated but as relational, just as
mother tongue and ethnicity are not characteristics of individuals orgroups, but are indexical of relations, including power relations, between
them and other people. WWF has identified nearly 900 ecoregions. 238 ofthem have been termed "Global 200 Ecoregions" because they are found"to be of the utmost importance for biological diversity" (ibid.). Most ofthem are in the tropical regions, just as languages are. Eric Smith's (2000:
107) account based on the 12th edition of the Ethnologue shows that
55.6% (3,630) of the world's endemic languages are in the tropical forest
regions.
Another global measure is biodiversity hotspots: "relatively small
regions with especially high concentrations of endemic species" (thedefinition is from Skutnabb-Kangas, Maffi & Harmon, 2003: 55). This
concept was created by Norman Myers; see Center for Applied
Biodiversity Science, http://www.biodiversityhotspots.org/xp/Hotspots).
2.3. Threats to diversities“In the last five hundred years about half the known languages of the world
have disappeared”, according to Hans-Jürgen Sasse (1992: 7). The most
optimistic prognoses of what is happening to the world's languages
suggest that around the year 2100 at least 50% of today’s close to 7,000
spoken languages may be extinct or very seriously endangered (withelderly speakers only and no children learning them). This estimate,originating with Michael Krauss (1992) is also used by UNESCO (see, forinstance http://portal.unesco.org/culture/en/ev.phpURL_ID=8270&URL_DO=DO_TOPIC&URL_SECTION=201.html, or the
position paper Education in a Multilingual World, UNESCO 2003c).

Pessimistic but still completely realistic estimates claim that as many as
90-95% of today's spoken languages may be extinct or very seriously
endangered in less than a hundred years' time. This is Krauss' estimate
today (e.g. 1996, 1997; see also Krauss, Maffi, and Yamamoto 2004).
UNESCO's Intangible Cultural Heritage Unit’s Ad Hoc Expert Group on
Endangered Languages (see UNESCO 2003a; see also UNESCO 2003b, c)
uses this more pessimistic figure in their report, Language Vitality andEndangerment (UNESCO 2003a). There may be only 300 to 600 oral
languages left as unthreatened languages, transmitted by the parent
generation to children. These would probably include most of thoselanguages that today have more than one million speakers, and a few
others. Almost all languages to disappear would be Indigenous languages,
and most of today’s Indigenous languages would disappear, with the
exception of very few that are strong numerically (e.g., Quechua, Aymara,Bodo) and/or have official status (e.g., Māori, some Saami languages).
Still more pessimistic estimates suspect that only those 40-50 languages
will remain in which people can, within the next few years, talk to theirstove, fridge and coffee pot, i.e. those languages into which Microsoft
software, Nokia mobile phone menus, etc., are being translated (Rannut2003). Our 2005 printer has some instructions in 32 languages, including
some fairly small in numbers like Estonian, Latvian and Lithuanian. One
could also use the number of languages into which Harry Potter films arebeing dubbed - Catalan-speaking children in Barcelona, Catalunya, staged
a huge demonstration demanding that the films be dubbed into Catalan.
Nobody knows what will happen to the world's Sign languages. There istoday no idea of how many Sign languages there are. The 14th version of
the Ethnologue only listed 114 Sign languages – a veritable
underestimation. There are Deaf people everywhere in the world, andwhere hearing people have developed spoken languages, Deaf people
have developed Sign languages. These are in every respect full languages(see, e.g. Lane 1992, Ladd 2003). The World Federation of the Deaf
(www.wfdeaf.org) estimates that there are some 70 million Deaf people in
the world. Only in Aotearoa/New Zealand does a Sign language have anofficial status similar to the other official languages (in this case English
and Māori). In a dozen countries Sign languages are mentioned in theconstitution.
Today, linguistic diversity is disappearing much faster than biodiversity.
According to conservative (i.e. optimistic) assessments, more than 5,000
species disappear every year; pessimistic evaluations claim that the figure
may be up to 150,000. Using the most “optimistic” estimate of both thenumber of species (the high figure of 30 million) and the killing of species(the "low" figure of 5,000/year), the extinction rate is 0.017% per year.
With the opposite, the most “pessimistic” estimates (5 million species;
150,000/year disappear), the yearly extinction rate is 3%.
On the other hand, researchers who use the high extinction rates often
also use higher estimates for numbers of species. If the number of species
is estimated at 30 million and 150,000 disappear yearly, the rate would be
0.5% per year. Many researchers seem to use yearly extinction rates whichvary between 0.2% (“pessimistic realistic”) and 0.02% (“optimistic realistic”- these are our labels).

If we disregard the cumulative effect and do a simplified calculation,according to the “pessimistic realistic” prognosis, then, 20% of thebiological species we have today might be dead in the year 2100, in ninety
years' time. According to the “optimistic realistic” prognosis the figure
would be 2%. Optimistic estimates, then, state that 2% of biological
species but 50% of languages may be dead (or moribund) in a 100 years'
time. Pessimistic estimates are that 20% of biological species but 90%of languages may be dead (or moribund) in ninety years' time.
Obviously the figures for extinction for biological species are muchhigher if we only take mammals, or birds, or only animals and plants - andthese are the species best described by natural scientists - cuddly koalas
are more interesting for most funders than slimy algae or invisible
bacteria (agro-biotech corporations are an exception). But since we know
very little about the relationships enabling healthy ecosystems (seeRapport, 1989) to be maintained, we need to use the total figures.
We could summarise the three main reasons for the disappearance of biodiversity as
follows:- The poor and powerless economic and political situation of people livingin the world’s most diverse ecoregions;- Habitat destruction through logging, spread of agriculture, use ofpesticides & fertilisers, deforestation, desertification, overfishing, etc. (seeDiamond, 2005).
- Knowledge about how to maintain biodiversity and use naturesustainably disappears with disappearing languages.
It is especially the explication of the third reason that we turn to next.
3. Relationships between linguistic diversity and biodiversity
3.1. A correlational relationshipA comparison of the world's linguistic and biological megadiversity
countries shows a very high overlap; both languages and biological species
become thicker on the ground the closer to the equator one moves, andarctic areas have fewer species and languages. Conservationist David
Harmon was probably the first scholar ever to put figures on the highcorrelations between biodiversity and linguistic and cultural diversity(1995).
When assessing the correlational relationship between biodiversity
and linguistic diversity, we can use detailed types of correlation, withcertain species or species groups as indicators, as Harmon did. In
addition, we can use the more global measures of biodiversity presented
above. Harmon compared the top 25 countries in the world with thelargest numbers of, on the one hand, endemic languages (languages
unique to a particular country; some 83-84% of the world’s languages areendemic), and on the other hand a number of indicators of biodiversity,
such as endemic higher vertebrates (mammals, birds, reptiles andamphibians) or flowering plants. 16 countries (of the 25) are on bothlanguages and vertebrates lists, a coincidence of 64%. "It is very unlikelythat this would only be accidental", Harmon concludes (1995: 6). He got
similar results with flowering plants and languages: a region often has
many of both, or few of both. The same is true for butterflies andlanguages, and birds and languages, etc. The conclusion is that at least
when using the species mentioned as indicators, there is a high correlation
between countries with biological and linguistic megadiversity (see also
Harmon 2002; Skutnabb-Kangas, Maffi & Harmon, 2003: 41 have later
added some other biodiversity indicators). A Framework for an Index of
Biocultural Diversity being prepared by David Harmon and Jonathan
Loh shows many detailed correlations still more clearly.
Of the 6,867 ethnolinguistic groups in the world (according to thedefinition presented above), some 67% (4,635) were found in the Global
200 Ecoregions (Oviedo & Maffi 2000: 1-2). With many more detailed
measures counted, the conclusion in the Executive Summary of Oviedo &Maffi, 2000 (p. 2) is as follows:
Correlations between Global 200 ecoregions as reservoirs of highbiodiversity and areas of concentration of human diversity areclearly very significant, and unequivocally stress the need to involve
indigenous and traditional peoples in ecoregional conservation
work. Furthermore, there is evidence from many parts of the worldthat healthy, non-degraded ecosystems - such as dense, little
disturbed tropical rainforests in places like the Amazon, Borneo or
Papua New Guinea - are often inhabited only by indigenous andtraditional peoples (emphasis added).
This also means that where we others have settled, meaning often intemperate climates, we have been a disaster to the world's biodiversity.
We would obviously also have colonised and inhabited those areas which
are still today relatively less degraded, had we been able to. Jarred
Diamond shows convincingly that what has kept us out is the fact that we
westerners have not been able to manage the climate (Diamond 1991,
1998). Even if this is true of some relatively biodiversity-poor areas too,such as the arctic areas, mostly we are talking about the biodiversity-richtropics.
3.2. Towards causality in biocultural/biolinguistic relationships
But the relationship between linguistic and cultural diversity on the one hand and biodiversity on
the other is possibly not only correlational. There seems to be mounting evidence that it might becausal. Ethnobiologists, human-ecologists and others have proposed “theories of ‘humanenvironment co-evolution’”, including the assumption that “cultural diversity might enhancebiodiversity or vice versa” (Maffi 1996): biodiversity in the various ecosystems and humans
through their languages and cultures have mutually influenced each other (e.g. Maffi, 2001;
Maffi et al., 1999, Skutnabb-Kangas, Maffi & Harmon, 2003; see also www.terralingua.org).
Neither type of diversity can probably be seen directly as an independent variable in relation tothe other. But linguistic and cultural diversity seem to be decisive mediating variables insustaining biodiversity itself, and vice versa, for as long as humans inhabit the earth.
But the evidence for a correlational relationship between biodiversity
and linguistic and cultural diversity does not prove anything about acausal relationship. For "proving" this causal relationship, several typesof knowledge would be needed. Some exists, some we have only partiallyat the moment; many issues have not been investigated yet. But thecriteria and the whole nature of the evidence obviously also depend on

the kind of scientific paradigms used. Likewise, whether already existing
evidence is seen as sufficient to lead to rapid action depends on whether
short-term corporate profit or the Precautionary Principle prevails, just to
take two possibilities.
As soon as humans came into existence, we started to influence therest of nature (see Diamond, 1998 for a fascinating account on how; seealso Cavalli-Sforza, 2001). Today it is safe to say that there is no “pristine nature” left - alllandscapes are cultural landscapes; they have been and are influenced by human action, eventhose where untrained observers might not notice this immediately. The concept of Terra
nullius ( = empty land) has finally been invalidated.
But the various ways that different peoples influence theirenvironments were and are filtered through their cultural patterns - wecan, for example, think of simple examples, comparing the attitudes tothe meat of cows, pigs, dogs or rats as human food, and the implicationsof this to the occurrence, spread and life conditions of the animals. Or
while more than 40,000 edible plants were known to the Aboriginal
inhabitants of South Australia, very few of them have found their way tothe plates of the European invaders. The Europeans have neither
lexicalised these items of food nor used them (Mühlhäusler, 2003: 59). If
one does not “see” them or sees them as “weeds” (see Crosby, 1994),
they are more likely to disappear. We have a similar but smaller-scaledifference in the use of mushrooms between the Finns and the Germans
on the one hand - they name and use mushrooms - and the British on theother hand who don't.
On the other hand, local nature and people's detailed knowledge
about it and use of it have influenced the perceptions, cultures, languages
and cosmologies of the people who have been dependent on it for theirsustenance. To remain with food examples, if the areas where people
have lived for a long time have plenty of animal protein but little of plant
protein as, for instance, in the Arctic areas, it is unlikely that religions
which support vegetarianism could have developed - and they haven't.
UNEP's (United Nations Environmental Programiv, http://www.unep.org/) mega-volume,
Cultural and Spiritual Values of Biodiversity. A Complementary Contribution to the
Global Biodiversity Assessment (Posey, ed. 1999) summarises some of this evidence of
causality. Likewise, articles in On Biocultural Diversity. Linking Language, Knowledge andthe Environment (Maffi, ed., 2001) illustrate it.
This relationship and mutual influence between all kinds of diversities
is of course what most indigenous peoples have always known. Some
describe their knowledge in the UNEP volume. The conservation traditions
that promote the sustainable use of land and natural resources,
expressed in the native languages, are, “what Hazel Henderson called‘the cultural DNA’ that can help us create sustainable economies inhealthy ecosystems on this, the only planet we have (Gell-Mann, 1994:
292)”, quoted in Nations (2001: 470).
3.3. Traditional ecological knowledge encoded in small (indigenous andlocal) languages and its disappearance
To discuss this indigenous knowledge and its present uses further and tohighlight its disappearance, we need first to remind ourselves of the factthat the least biodiversity-wise degraded areas tend to be areas inhabitedby indigenous peoples only. Since the degradation is mainly created byhumans, a conclusion is that those indigenous peoples who have not beencolonised by others, have been and are important agents in themaintenance of biodiversity. The knowledge they have when interactingwith (the rest of) nature in non-degrading ways is part of what has beencalled "traditional ecological knowledge" (TEK),
in-depth knowledge of plant and animal species, their mutual
relationships, and local ecosystems held by indigenous or traditional
communities, developed and handed down through generations(Skutnabb-Kangas, Maffi & Harmon 2003, Glossary, p 56).
The classifications of animals and plants obviously reflect theenvironment where people live. But they develop over a long time, andthis largely explains why indigenous peoples have not necessarily been
good guardians of their environments. Even in terms of vocabulary fordescribing the environment, Mühlhäusler (2003) estimates on the basis of
his pilot studies on "desert islands" and Creole situations (Norfolk Island,
Mauritius, New Zealand, St Helena, St Kitts and several others, p. 59) that"about 300 years are needed for a match between a language and thebiological environment of its speakers to come about" (ibid.: 37). Before
that there is "a major discrepancy between what people can name andwhat they need to name to sustain their island environment" (ibid.: 59).
In situations where people move to a new place with their old
language, this is initially "ill-suited to the task of talking about" the newenvironment (ibid.: 46) because of the "considerable initial mismatch
between linguistic categories and natural boundaries" (ibid.: 59). The
likelihood is that they may ruin much of that environment before they
start to understand, classify and name it, regardless of whether there are
already other people living there who had a "perfect" understanding of
the biodiversity around them (like in Australia) or not (as in Aotearoa/New
Zealand when the first Māoris arrived a millennium ago). In the absenceof lexicalisation, people "under-utilize or over-exploit their environment"(ibid.: 59).
Even if the vocabulary is there, people may still be "environmentally
illiterate", i.e. unable to name animals, plants and features of thelandscape (Mühlhäusler 2003: 41), for instance in urban contexts or if
their technologically oriented worldview sees nature as a passive"ecomachine", for humans to use and exploit as they please - this is partly
what enables the "growthism ideology" (ibid.: 132) to continue.
But it is not only the vocabulary of languages that is culture-specific Mühlhäusler also claims, with many others (e.g. Michael Halliday, 2001)
that grammars are "fossilized experience". Each grammar "can be seen as
a repository of past experience, as the outcome of a very long process ofadaptation to specific environmental conditions" (ibid.: 120); this is a
result of the fact that "each language is functionally integrated with a vastarray of grammar-external parameters" (ibid.). Discussing various aspectsof grammar (pronouns, transitivity, passives, ergativity, tense/time,
abstract nouns and nominalizations, binominals, counterfactuals),Mühlhäusler shows how various perspectives on the world are privilegeddepending on the grammatical structures of various languages. This also
implies that "there could be a discrepancy between past functionality andpresent day requirements" (ibid.: 100)v. His arguments about thegrammatical structures of the "European" languages making it easier, forinstance through nominalizations, to construct issues like polluting ascommodities to be bought an sold - the Kyoto negotiations come to mind and to hide agency - things just happen - are amply illustrated in several
detailed articles in the Ecolinguistic Reader (2001), edited by Fill and
Mühlhäusler.
Another type of proof of causality could be to be able to show that it
is likely that the knowledge about how to maintain aspects of biodiversity(and thus the practice of doing it) disappears if a language disappears.
Luisa Maffi showed in her doctoral dissertation (1994) that nuances in theknowledge about medicinal plants and their use disappear when
indigenous youth in Mexico become bilingual without teaching in andthrough the medium of their own languages - the knowledge is nottransferred to Spanish which does not have the vocabulary for thesenuances or the discourses needed (see also Nabhan, 2001, Carlson,
2001).
Pekka Aikio, the President of the Saami Parliament in Finland(personal communication, 29 November 2001) reported that Finnish fishbiologists had just "discovered" that salmon can use even extremely small
rivulets leading to the river Teno, as spawning ground - earlier this wasthought impossible. Pekka stated that the Saami have always known this the traditional Saami names of several of those rivulets often include theSaami word for "salmon spawning-bed". This is ecological knowledge
inscribed in indigenous languages. This example shows that it is possible
for Western researchers to discover for themselves the knowledge thathas already been encoded in the indigenous language - but, as in thiscase, probably at least a millennium later than the indigenous people had
it. But in many cases, the knowledge may disappear in ways where awestern scientific retrieval is impossible, for many reasons, including all
those material reasons which are causal factors in the disappearance ofboth biodiversity and linguistic diversity. And in many cases a rediscoveryof the knowledge may come too late in any case.
3.4. Processes in the disappearance of traditional knowledge throughhierarchisation of languages and knowledges in education
Some critics accuse those worried about endangered languagesvi ofwanting to preserve/conserve indigenous and minority languages andknowledges in some kind of museal conditions. According to them, we arepreventing indigenous peoples from becoming modern, implying that theywant to assimilate into larger, mostly western, languages and cultures, atthe cost of their own. "Traditional" to these researchers still seems tomean backward, static, non-scientific, foreclosing all economic and social
mobility and opportunitiesvii.
In fact, in many cases, as Oviedo and Maffi state (2000: 6), TEK "isfound to be more complete and accurate than Western scientificknowledge of local environments" (ibid., 6-7). Several articles in Maffi(ed., 2001) and Posey (ed., 1999) also testify to this. Few people seem toknow, for instance, that Linnéan categories were based on ancient Saami
categorisation of nature (Gutierrez-Vazquez, 1989: 77). This knowledge isin no way static either, as the Four Directions Council in Canada (1996,
quoted from Posey, 1999: 4) describes:
What is "traditional" about traditional knowledge is not its antiquity,
but the way it is acquired and used. In other words, the social
process of learning and sharing knowledge, which is unique to eachindigenous culture, lies at the very heart of its "traditionality". Muchof this knowledge is actually quite new, but it has a social meaning,
and legal character, entirely unlike the knowledge indigenous
people acquire from settlers and industrialized societies.
And it is exactly this transmission process that is at grave risk as soon as
indigenous children attend schools where their languages are not themain teaching languages and where their cultural practices do notpermeate the learning processes. This is linguistic and cultural genocide,according to articles IIb and IIe of the UN 1948 Genocide Convention (seeSkutnabb-Kangas 2000). The 2002 report Science, Traditional
Knowledge and Sustainable Development by the International
Council for Science (ICSU - see www.icsu.org) shows very clearly that TEK
is seen as containing a great deal of knowledge unknown to and of utmost
importance to (western) science, and that scientists are worried about thediminishing transmission of it. ICSU's stance agrees fully with theimportance of linguistic and cultural human rights in education even if
they do not formulate their worries in human rights terms:
Universal education programs provide important tools for human development, but they
may also compromise the transmission of indigenous language and knowledge.
Inadvertently, they may contribute to the erosion of cultural diversity, a loss of social
cohesion and the alienation and disorientation of youth. […] In short, when indigenous
children are taught in science class that the natural world is ordered as scientists believe it
functions, then the validity and authority of their parents’ and grandparents’ knowledge isdenied. While their parents may posses an extensive and sophisticated understanding of thelocal environment, classroom instruction implicitly informs that science is the ultimate
authority for interpreting “reality” and by extension local indigenous knowledge is second
rate and obsolete. […] Actions are urgently needed to enhance the intergenerationaltransmission of local and indigenous knowledge. […] Traditional knowledge conservation
therefore must pass through the pathways of conserving language (as language is an
essential tool for culturally-appropriate encoding of knowledge). (from various pages in
ICSU 24).
Since TEK is necessarily encoded into the local languages of the peoples whose knowledge it
is, this means that if these local languages disappear, without the knowledge being transferred
to other, bigger languages, the knowledge is lost. We then have to ask the two questions: Has
the knowledge been transferred to other languages? The answer is No. Are the languages
disappearing? The answer is Yes. Michael Warren, one of the people first using the concept ofindigenous knowledge, echoes ICSU when he concludes (2001: 448):

Of major concern is the rapid loss of the knowledge of many communities as universal
formal education is enforced with a curriculum that usually ignores the contributions oflocal communities to global knowledge. The loss of knowledge in linked indelibly tolanguage extinction since language is the major mechanism for preserving and transmitting
a community’s knowledge from one generation to another.
In this perspective, the first conference investigating this relationship between humans and theirenvironment “Endangered Languages, Endangered Knowledge, Endangered Environments” (seeMaffi (ed.) 2000) stressed “the need to address the foreseeable consequences of massive
disruption of such long-standing interactions” [i.e. the human-environment co-evolution]” (Maffi
1996). The processes of language loss also “affect the maintenance of traditional environmental
knowledge - from loss of biosystematic lexicon to loss of traditional stories” (ibid.). Thus loss oflanguages on a massive scale may also entail loss of some of the basic prerequisites formaintaining life on the planet.
Linguistics in its structuralist forms has tended until recently toconcentrate on the forms of language rather than its social functions.
Sociolinguistics and the sociology of language have brought in contexts ofuse but seldom addressed issues of language and power. Such key
concepts as diglossia have suffered from the absence of any anchoring insocial theory, as indeed has much work in language planning (Williams
1992). As a result there tends to be little clarification of the causes of
linguistic hierarchies or of the implications for language ecology. Languages
do not in fact “spread” without agents, just as language “death” and“attrition” are not “natural” processes, analogous to biological processes:
agents have often willed and caused linguicide and continue to do so.
Dominant languages are legitimated through processes of hegemonic
saturation in public discourse, the media and public education to the point
where their learning, involving subtractive language shift (i.e. adopting thedominant language involves loss of the first languageviii), is accepted as
natural, normal and incontestable. Linguistic hierarchies and a stratifying
education system reflect monolingual ideologies, a particular model ofsociety and particular interests, namely those of dominant groups.
The maintenance and continuous reconstruction of these hierarchicalrelationships between users of languages usually involves a pattern of
stigmatisation of dominated languages (barbarian, patois, ...), glorificationof the dominant language (the language of reason, logic, progress etc) anda rationalisation of the relationship between the languages and theirspeakers, always to the benefit of the dominant one and making it seem as
if they are “helping” the dominated ones. Knowledges encoded in andtransmitted through these languages are hierarchised through similar
processes. “Aid” organisations and many NGOs often seem to function as
yesterday’s missionaries, with similar consequences. Linguistic hierarchies
reminiscent of the colonial period underpin much World Bank and IMF education policy, whichcurrently sets the tone for "aid" alongside notoriously anti-social, poverty-inducing structuraladjustment policies. A study of the World Bank's investment in education reveals that there is arhetoric of support for local languages, but in fact the policies serve to consolidate the imperial
languages in Africa (Mazrui 1997). Linguistic imperialism is underpinned by the belief that only
European languages are suited to the task of developing African economies and minds, the falsityof which many African scholars have shown (Ansre, Bamgbose, Kashoki, Mateene, Ngũgĩ, seereferences in Phillipson 1992).

4. Work to counteract ecolinguistic threats and promote the survival of diversities
Signed by 150 states at the 1992 Rio Earth Summit, the Convention on
Biological Diversity, dedicated to promoting sustainable development, isthe most important international treaty on ecology. It recognizes that
biological diversity is about more than plants, animals and microorganisms and their ecosystems – it is also about people and theirenvironment (see http://www.biodiv.org/convention/default.shtml), andhere languages are included. In its Article 8j about traditional knowledge,
each of the states promises,(j) Subject to its national legislation, respect, preserve and maintainknowledge, innovations and practices of indigenous and local
communities embodying traditional lifestyles relevant for theconservation and sustainable use of biological diversity and promote
their wider application with the approval and involvement of theholders of such knowledge, innovations and practices and encourage
the equitable sharing of the benefits arising from the utilization ofsuch knowledge, innovations and practices.
Further work on the Convention stresses the interlocking of language andecology in traditional knowledge and its inter-generational transfer:
Traditional knowledge refers to the knowledge, innovations andpractices of indigenous and local communities around the world.
Developed from experience gained over the centuries and adapted to
the local culture and environment, traditional knowledge istransmitted orally from generation to generation. It tends to becollectively owned and takes the form of stories, songs, folklore,
proverbs, cultural values, beliefs, rituals, community laws, local
language, and agricultural practices, including the development ofplant species and animal breeds (seehttp://www.biodiv.org/programmes/socio-eco/traditional/).
Several international organisations work for the promotion of linguistic diversity. Some collectand/or analyse the basic data (e.g. the Ethnologue, or UNESCO (Martí et al., 2005),
International Clearing House for Endangered Languages in Tokyo, all UNESCO’s
endangered languages-related projects (start from http://portal.unesco.org/culture/en/ev.phpURL_ID=8270&URL_DO=DO_TOPIC&URL_SECTION=201.html). The European Bureau
for Lesser Used Languages, EBLUL (www.eblul.org), is an example of proactive work tocounter the minorisation of languages in European Union countries. Terralingua(www.terralingua.org) is devoted to preserving the world's linguistic diversity and toinvestigating links between biological and cultural diversity and its web-site has lists of and links
to organisations working with both endangered languages, including various types of “salvage
operations”, and with language rights.
Language scholars who have discussed the ecology of languages, starting with Trim andHaugen (e.g. 1972) have been aware of the threat and many are trying to counteract it, throughanalysis and action (see, e.g. Brenzinger (ed.) 1992, Fill 1993, 1998, Fishman 1991, Grenoble &Whaley 1996, 1998, Hinton 1994, Huss 1999, Mühlhäusler 1996, Phillipson & Skutnabb-Kangas

1996). In the struggle against linguicism (Skutnabb-Kangas, 1988), linguistic imperialism(Phillipson, 1992) and domination, speakers of threatened languages are using many strategies(see the entry Language Rights). Revitalisation and even the reclaiming of earlier minorised
languages are also taking place. It is a promising development that organisations and projects
such as UNEP or 2010 Biodiversity Indicators Partnership now accept the multidisciplinary
ecolinguistic principle that we in Terralingua have advocated, expressed by the latter in astatement that summarises many of the arguments of this entryix:
There is a fundamental linkage between language and traditional knowledge related tobiodiversity. As languages go extinct, there is an irrecoverable loss of unique cultural,
historical and ecological knowledge. Local and indigenous communities have elaborated
complex classification systems for the natural world, reflecting a deep understanding of
local flora, fauna, ecological relations and ecosystem dynamics. This traditional ecologicalknowledge is both expressed and transmitted through the local or indigenous language.
When young people no longer learn the language of their ancestors, or know it only
partially and instead learn and use another majority or dominant language, the special
knowledge incorporated in their ancestral language is often not transferred to the dominantlanguage that replaces it. Commonly, this is because the dominant language does not havethe vocabulary for this special knowledge, or even because the very situations in which thiskind of knowledge and its relevance for survival are learned do not occur in the dominantculture. Information on status and trends of numbers of speakers of indigenous languages
may therefore be used as a proxy for measuring trends in the status of traditional
knowledge, innovations and practices.
4. To conclude
Colin Baker sums up the importance of ecological diversity in his review ofSkutnabb-Kangas, 2000 (Baker, 2001: 281).
Ecological diversity is essential for long-term planetary survival.
Diversity contains the potential for adaptation. Uniformity can
endanger a species by providing inflexibility and unadaptability. As
languages and cultures die, the testimony of human intellectual
achievement is lessened. In the language of ecology, the strongest
ecosystems are those that are the most diverse. Diversity is directly
related to stability; variety is important for long-term survival. Our
success on this planet has been due to an ability to adapt to different
kinds of environment over thousands of years. Such ability is born out
of diversity. Thus language and cultural diversity maximises chances ofhuman success and adaptability.
Biocultural diversity is thus essential for long-term planetary survival
because it enhances creativity and adaptability and thus stability. We
envisage a balanced ecology of languages as a linguascape whereinteraction between users of languages does not allow one or a few tospread at the cost of others and where diversity is maintained for the
long-term survival of humankind (as Baker, 2001 suggests). If the detailed
knowledge, encoded in small indigenous languages, about the complexities of biodiversity andhow to manage ecosystems sustainably, is to be maintained, the languages and cultures need tohave better conditions: they need to be transferred from one generation to the next, in families

and through schools. Researchers need to understand and challenge theunequal power relationships implicated in the destruction of language
ecologies.
If global linguistic diversity is not to suffer irreparable attrition, as a result of linguistic
genocide, major changes are needed in educational language policy. Strategies to counteract the
linguistic dominance and hierarchisation that may ultimately lead to the disappearance of the
majority of today's languages are urgently needed. Today's efforts are completely insufficient.

Using “killed” rather than “dying” or “disappearing” highlights the fact that itis neither “natural” (in the same sense as for biological organisms) nor
agentless for languages to disappear. And if there are agents responsible for
and/or contributing to the killing, the scope for action may also be broader than
if one thinks one is fighting against a “natural development”. Processes leading
to linguistic assimilation and therefore often languages disappearing include
linguistic genocide. Besides, all the verbs, kill, disappear, die, are equallymetaphorical.

Subtractive spread of languages - incoming language first displaces, thenreplaces original languages. Often a result of linguistic imperialism (seePhillipson 1992).
Subtractive language learning - a new (dominant/majority) language islearned at the cost of the mother tongue which is displaced, with a diglossic
situation as a consequence, and is sometimes replaced. The person's total
linguistic repertoire does not show (much) growth as a result of the learning.
Additive spread of languages - incoming language is initially used for new
functions ('neoplacement'), but does not replace original languages which
continue to be used and developed, even if some diglossia may occur. Later,
terms in the original language may develop for the neoplaced concepts.
Additive language learning - a new language is learned in addition to themother tongue which continues to be used and developed. The person's total
linguistic repertoire is extended (Skutnabb-Kangas 2000: 72). Seeing somelanguage rights as human rights, with the protection that these enjoy, cansupport additive rather than subtractive (or replacive, Haugen, 1972) language
learning and facilitate the maintenance of linguistic diversity.
