Cows are actually much worse for the environment, what with their expulsion of gas that affects the ozone layer.
Why doesn't the article say we should kill all the cows and stop eating beef?

Truthfully, humans are the worst leeches on the planet...we rape and pillage the earth without a thought to the consequences...and we're supposedly the smartest animal on the earth...

But I actually like humans, so they and their pets can stay!!
