The groundbreaking 2014 documentary Cowspiracy presents shocking truths about the effects of industrial animal agriculture on the planet. The leading cause of deforestation, rainforest destruction, greenhouse gas production, water consumption and pollution, habitat loss, species extinction, ocean dead-zones, topsoil erosion, and a host of other environmental ills, animal agriculture is the biggest issue facing the planet today. And one of the most controversial environmental secrets in the world of conservation.

Filled with anecdotes, statistics, research, interviews with the filmmakers and contributors, and unabridged transcripts from the film, this companion book supplements and expands upon the documentary in every way. With all this and more, The Sustainability Secret reveals the absolutely devastating environmental impact large-scale factory farming has on our planet and offers a path to global sustainability for a growing population.
