I'm a junior, majoring in Geo, and (as you can see below), Environmental
Studies.  Just about all the students in the department here are interested in
environmental issues, and some, myself included, are very active in the student
environmental movement, which professors in our Geo Dept. support, too.

The most troubling issue for me regarding the exploitation (right or wrong) of
natural resources was rooted in the question of pure vs. applied science.  I
feel torn because, on the one hand, it is our never ending application of such
beautiful principles such as those in theoretical physics (not that I'm going
to pretend to have the foggiest idea about them) that led to the nuclear arms
race and nuclear contamination around the globe.  On the other hand, our way of
life is firmly rooted in combustion of fossil fuels, and if we were to take
them away today, society would be seriously threatened.  As a fellow
undergraduate, my advice to you would be to learn and do what you want. 
Geologists don't have to be exploiters, and I would be willing to bet that
there are a lot of economic geologists out there with a profound respect for
nature.  In fact, I know an economic geologist who is a fervent animal
lover and supports the environmental movement. 
 Your behavior only depends on you.

In any case, I made the decision to join geology because it is so diverse, and
you get to use all the other disciplines in your study, and as a student (even
in the midst of finals) I would heartily recommend the science to you.

The problem is that rocks, like many other pressure sensitive brittle 
materials, do NOT usually fail in shear when unconfined - rather, a sample 
will split with "tensile" fractures perpendicular to the zero stress direction.
Who put you onto this?

That's a pretty ill-considered and stupid flame, and I take great offense at it,
having worked in the field of paleomagnetism.  First of all - if no one alive
today was alive for the "last one" how do we know the field ever reversed?
By scienctific research, of course, same reason we know why the reversals do not
cause big problems.

Nope.  The 20% or so of the field that remains will still generate a
powerful magnetosphere.  That's why studies of extinctions during
reversals and excursions find only a few and only in polar regions.

> practical problems, Navigation by many of the earths migrating species

Yes, animal migration may be affected, but most animals
that use magnetic navigation also have other systems - landmarks, using
the sun, etc.
Very little human navigation in magnetic these days - too inaccurate.
Communication does not really rely on the magnetic field either, just
the ionosphere, which will change, but not disappear.

The average frequency is currently 5 per million years, but the shortest known
interval is about 30,000 years.  There are a lot of reversals, at least
a half dozen since man appeared 2 million years ago.  (The most recent
interval which we are living in, is unusually long at 700,000 years).
Clearly, with the field reversing all the time like this, there is very
little adverse effect, otherwise there would be evidence of it.

  I think almost all geologists have a profound respect for nature, and in
my experience, so do most all oil company employees, especially offshore.
Certainly this seems true of the geologists.  It's certainly nice to have
the company (Exxon, Shell, etc.) match your charitable contribution to
the Nature Conservancy 3 to 1.

  You'd obviously be surprised how many Sierra Club members work in the
oil industry.  

  YOU determine your stance, not your employer.  You determine what you
stand for, and where you want to try to make a difference.

I did a degree in Geology some years ago at Swansea University (Wales).  They
aimed to turn out what they called "rounded" geologists.  In retrospect this
doesn't seem to have been a good idea as the companies advertise for specific
expertise, even from new graduates.  Hydrogeology (as someone said earlier)
seems to be a good bet these days and micropaleontology (for mud logging and
like jobs in oilfields) looks good too.

I tried but never managed to get a job as a geologist or geophysiscicst and am
now a computing research scientist.  However, I *never* regret having studied
Geology, imagine doing a computer science degree! :-)

I did work for seven years as a mining software consultant (working on things
like ore reserve estimation (and later artificial intelligence)) for a
multinational mining company.  I had some moral concerns that came to a head
when I was asked to travel to a couple of the mines in a political blackspot.
I was worried about exploitation (more of people than the environment) and
decided that If I was so worried I should go and see what it was all about
rather than put my head in the sand.

I'm glad I went.  The company was making tremendous strides in bringing
equality to the workforce and I saw this personally right up to general
management level.  There was also a lot of work being done to make the
workplace safe and comfortable (not always easy in a mine). I was really
pleased to be a part of all that, I doubt that the company was all good but I
saw something that I was glad to be a part of.   

On the environmental front the regular IMM (Institution of Mining and
Metallurgy) publications never used to contain much about environmental
concerns but this is changing.  It is the people working in the oil/mining
companies that make the decisions and form the policies.  I imagine that a
geologist on the inside will have more clout than person X on the outside, if
you want to do geology, go for it and use your influence and training for the
good of the environment and the people.

A QUESTION:- In travels to and dealing with a number of mines , geologists and
mining engineers I found that there was a *lot* of rivalry between geologists
and mining engineers (not all of it good natured).  I suspect that being a mine
geologist could be a rather fraught occupation.  What's it really like out
there? 

Cheers

Put them at the beginning or end.

Journalists are largely very busy rush rush sort of people.  Anything
that will get used had better be very short so they can read it while
trying to make a deadline.  It also better be cheap to give them over
and over again because they are continually rotating jobs and the new
people need to get everything over again.  Its easier for them to ask
us for the info then to look it up themselves so we tend to answer
these questions constantly.  This does not apply to the real science
writers, some of which are great, but to the bulk of news reporters.

I read in Jan'93 Sky And Telescope about the dating of the Yucatan

that the magnetic field was reversed at that time.
