A growing consensus among scientists, doctors, environmentalists, and animal rights activists suggest that our current system of food — specifically meat — production is not sustainable
This is like saying there i a consensus of scientists that say man is causing global warming. OH! WAIT! Now it's climate change. There are less than 2000 scientists that signed on to the UN document claiming that mans causes global warming.
There are almost 30,000 scientists refuting this claim. LINK
Go to the link and look on the left hand side at all of the signers of the petition to the Kyoto agreement of 1997. The news does not cover this story. I think 30,000 scientists is far greater than 2,000.
