Guess how many cows are killed every hour in the US, just so you can have your burger? A whopping 660 000 of them.

Paul McCartney, best known from his part in the Beatles, wants to change this. He believes we can fight global warming simply by not eating meat on Mondays.

McCartney supports the Meat Free Mondays campaign in order to encourage people to give up eating meat or at least to reduce their meat consumption. He states, “Having one designated meat free day a week is actually a meaningful change that everyone can make, that goes to the heart of several important political, environmental and ethical issues all at once.”

Sacrificing meat just once a week could cut greenhouse gas emissions by 20%, according to Greenpeace. But can sacrificing a burger or chicken sandwich just ONCE a week really affect change?

Depending on where and how it is produced the FAO estimates that the livestock industry is responsible for between 13.5 and 18 percent of global greenhouse gas emissions…Some of these are from the methane emitted from livestock. Half of all US water-usage is devoted to livestock, with each cow needing enough water to float a destroyer! Read the full story
