In Diet for a New America, John Robbins hypothesizes that there is enough food to go around, but that food is being wasted in America. Robbins believes that certain foods, particularly red meat, lead to the extinction of species, decimation of the rain forests, and the mining of topsoil. Important steps to take include buying local food and eating a primarily plant-based diet.
