This document discusses how one's diet can impact both personal health and the environment. It notes that 18% of greenhouse gases come from meat production, more than the 13% from all global transportation combined. Eating meat, especially beef, can contribute to deforestation in the Amazon rainforest to make room for soy crops used to feed livestock. However, getting enough protein does not require eating meat, as proteins are readily available from plants like beans, lentils, grains and nuts. Going meatless just one day a week can help the planet and one's health by reducing risks of diseases and increasing longevity. The document encourages taking a pledge to participate in Meatless Mondays.
