(Grist) Meat should be taxed to encourage people to eat less of it, thus reducing the production of global warming gases from sheep, cattle, and goats, according to a group of scientists.

The scientists’ analysis, published in the journal Nature Climate Change, takes the contentious step of suggesting methane emissions be cut by pushing up the price of meat through a tax or emissions trading scheme.
