In "Eating Animals," Jonathan Safran Foer discusses the concept of bio-industry, which he describes as a modern conflict waged against animals we consume. This industry views nature as an adversary to be conquered, leading to ethical and environmental concerns surrounding food production. Foer emphasizes the implications of prioritizing efficiency and profit over animal welfare and ecological balance.

By presenting eating animals in the context of war, Foer challenges readers to reconsider the ethical ramifications of their dietary choices. The bio-industry's approach often results in the exploitation of animals and degradation of the environment, prompting a call for reflection on the broader impact of our consumption habits.
