Besides trying to convince people to change their diets so we can get rid of more cows, other efforts seek to attack the emissions at the source. The Bill and Melinda Gates Foundation awarded a $4.8 million grant to a London-based company to develop a gas mask as a sort of carbon capture technology — on a cow. Other research is looking into food additives that go into the cows’ feed as a way to reduce the amount of emissions coming out of the animal.

In Ireland, dairy farmers were looking at possibly having to kill a lot of cattle to come into compliance with emission reduction targets.
