Types of Meat Matter
Beef is an order of magnitude harder on the environment than other types of meat. For example, it takes 27 times as much land. It takes 3.3 times as much feed. It takes 9 times as much water. It produces 2.5 times as much CO₂ greenhouse gas. Further because of their special cellulose-digesting four-chambered stomachs, cattle burp up enormous quantities of methane CH₄ a greenhouse gas 25 times more potent than CO₂. If you don’t want to give up meat entirely, at least switch to pork, lamb, goat, rabbit, chicken, eggs, fish… or even dairy.~ Roedy (1948-02-04 age:69) National Geographic source.
