Many of the organic farmers Pollan encounters developed their political ideals from the radicalism of the 1960s, which saw small-scale, sustainable farming as a way of maintaining a healthy relationship between humans and the world around them. The mid-twentieth century saw the development of new and more efficient synthetic fertilizers, but landmark dissenting works like Rachel Carson’s
Silent Spring (1962) also drew attention to the negative effects of such technological breakthroughs and helped found the environmentalist movement. But as Pollan shows, the utopianism of this historical moment later gave way to more practical considerations. The 1960s’ dream of sustainable collective agriculture looked increasingly less plausible in a globalized economy that required shifting vast amounts of food across long distances. Pollan also writes about two significant movements in twentieth-century political thought: animal rights and vegetarianism. In particular, Pollan engages closely with the work of Peter Singer, the world’s foremost philosopher of animal rights. Singer is a utilitarian, meaning that he believes the most ethical action is the one that maximizes “utility”—in the case of animal rights, maximizing the happiness of animals and avoiding hurting them. For him, this means treating animals (in many cases) as having equal rights as humans. Ultimately, Pollan finds this point of view too extreme. He also becomes skeptical of vegetarianism, a movement which steadily gained ground beginning in the 1970s, as a result of increasing ethical and environmental concerns about the eating of meat.
