To lower pollution, eat less beef

Raising livestock for the production of beef is clearly bad for the environment, but researchers didn’t know just how damaging it is until recently. Cattle for beef require 28 times more land and 11 times more irrigation water than is required for raising livestock for pork, poultry, eggs, and dairy, BBC reports. The researchers describe their estimates this week in the Proceedings of the National Academy of Sciences and suggest that dietary changes, like eating fewer hamburgers, could have a big environmental impact.
