A new UN report has found that cows are a bigger threat to the environment than cars, as they produce more greenhouse gases than cars, planes and all other forms of transport put together.
So this makes it easy. Humans need to wipe out cows in order for us to survive. Let the killing begin.
I suggest we need incentives, so how about the UN pays a bounty of say US20 per cow killed. That will solve global warming for only US$30 billion!
