What I found remarkable about this essay is that Latham provides establishment sources via links to back up his claims that the promotion of agribusiness is based on lies.
...what industry understands, and the food movement does not, is that what prevents total rejection of bland, industrialised, pesticide-laden, GMO food is the standard acceptance, especially in Western countries, of the overarching agribusiness argument that such food is necessary. It is necessary to feed the world.Hence, the solution is:
...the food movement could show that famine is an empty threat then it would also have shown, by clear implication, that the chemical health risks and the ecological devastation that these technologies represent are what is unnecessary. The movement would have shown that pesticides and GMOs exist solely to extract profit from the food chain. They have no other purpose. Therefore, every project of the food movement should aim to spread the truth of oversupply, until mention of the Golden Fact invites ridicule and embarrassment in the population, rather than fear.
