A food chain is a linear network of links in a food web starting from producer organisms (such as grass or trees which use radiation from the Sun to make their food) and ending at apex predator species (like grizzly bears or killer whales), detritivores (like earthworms or woodlice), or decomposer species (such as fungi or bacteria).
 A food chain also shows how the organisms are related with each other by the food they eat.
 Each level of a food chain represents a different trophic level.
 A food chain differs from a food web, because the complex network of different animals' feeding relations are aggregated and the chain only follows a direct, linear pathway of one animal at a time.
 Natural interconnections between food chains make it a food web.
 A common metric used to quantify food web trophic structure is food chain length.
 In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.
Traceroute is a 2016 Austrian/American documentary film directed by Johannes Grenzfurthner.
 The autobiographical documentary and road movie deals with the history, politics and impact of nerd culture.
 Grenzfurthner calls his film a "personal journey into the uncharted depths of nerd culture, a realm full of dangers, creatures and more or less precarious working conditions", an attempt to "chase the ghosts of nerddom's past, present and future."
 The film was co-produced by art group monochrom and Reisenbauer Film.
 It features music by Kasson Crooker, Hans Nieswandt, and many others.
Command and Control is a 2016 American documentary film directed by Robert Kenner and based on the 2013 non-fiction book of the same name by Eric Schlosser.
 It was released initially in the United States at the Tribeca Film Festival and then in the United Kingdom at the Sheffield Doc/Fest on June 11, 2016.
 It is based on the 1980 Damascus Titan missile explosion in Damascus, Arkansas between September 18–19, 1980.
 The film aired on the PBS network series "American Experience" on January 10, 2017.
Farm-to-table (or farm-to-fork, and in some cases farm-to-school) is a social movement which promotes serving local food at restaurants and school cafeterias, preferably through direct acquisition from the producer (which might be a winery, brewery, ranch, fishery, or other type of food producer which is not strictly a "farm").
 This might be accomplished by a direct sales relationship, a community-supported agriculture arrangement, a farmer's market, a local distributor or by the restaurant or school raising its own food.
 Farm-to-table often incorporates a form of food traceability (celebrated as "knowing where your food comes from") where the origin of the food is identified to consumers.
 Often restaurants cannot source all the food they need for dishes locally, so only some dishes or only some ingredients are labelled as local.
Merchants of Doubt is a 2014 American documentary film directed by Robert Kenner and inspired by the 2010 book of the same name by Naomi Oreskes and Erik M. Conway.
 The film traces the use of public relations tactics that were originally developed by the tobacco industry to protect their business from research indicating health risks from smoking.
 The most prominent of these tactics is the cultivation of scientists and others who successfully cast doubt on the scientific results.
 Using a professional magician, the film explores the analogy between these tactics and the methods used by magicians to distract their audiences from observing how illusions are performed.
 For the tobacco industry, the tactics successfully delayed government regulation until long after the establishment of scientific consensus about the health risks from smoking.
 As its second example, the film describes how manufacturers of flame retardants worked to protect their sales after toxic effects of the retardants were reported in the scientific literature.
 The central concern of the film is the ongoing use of these tactics to forestall governmental action to regulate greenhouse gas emissions in response to the risk of global climate change.
The California Center for Public Health Advocacy, located in Davis, California, is a nonprofit lobbying organization founded in 1999 by California’s two public health associations which, according to its website, "tackles the underlying factors that perpetuate childhood obesity and undermine parents’ desire to keep their children healthy: multibillion-dollar marketing and overwhelming availability of unhealthy foods and beverages, limited access to fresh fruits and vegetables in far too many communities, schools failing to provide quality physical education, cities designed for cars rather than pedestrians and bicyclists, and lack of safe places for children to play."
 They run the anti-soft drink website Kickthecan.info, which has launched a petition to the beverage industry to "be a (real) part of the solution" whose signatories include Laurie David, Michael Jacobson, Robert Kenner, and Marion Nestle, and are behind a number of soda tax bills in their home state, such as that introduced by Bill Monning in February 2013.
 Its executive director, Harold Goldstein, has written an opinion piece in the Los Angeles Daily News regarding what he considers the benefits of soda taxation.
 He has also authored a policy brief by the University of California Los Angeles.
 Goldstein has also authored an article calling for celebrities to "stop accepting sugary drink endorsements," as well as a commentary in the Journal of Public Health Policy regarding the reasons why scientific research is not easily transformed into public health policy, and about the CCPHA's campaigns to, among other things, remove soda and junk food from public schools.
 Goldstein has also gone on record as saying that sugary drinks "should be prohibited in all public places, including community centres and sports arenas."
 The Center has also published research concluding that were California Assembly Bill 669 to be passed, that "85 percent [of the money raised] or $1.4 billion, would be returned to counties, in proportion to their population, to pay for education and children’s health programs."
