Elon Musk: The animals are not gonna make any difference to global warming.

"The animals are not gonna make any difference to global warming. None. Zero. to global warming or the CO2 concentration atmosphere, really, if people eat fewer steaks, it doesn't matter. It's irrelevant. Irrelevant. I want to just be super clear about that. Yeah. Will not matter. You will not even be able to measure it. OK? That's how irrelevant it is.... And if somebody says it does make a difference, I'm like, how will you measure it? And if you can't even measure it, then it's bullshit."
