>Humanity isn't going to go extinct from climate change

Seems like the most likely way right now.

>Causes of climate change are fossil fuels

Yes, and fossil fuels are used in livestock production.

Through use of petrochemicals to produce feed and deforestation. 18% of GHG emissions are estimated to be from livestock and dairy production.

This article covers a lot of the usage: http://www.docbrownscience.com/uploads/4/8/7/2/4872895/food_....

I agree it contributes, but the problem is that fossil fuels are cheap and convenient. Getting rid of meat would delay the problem but not solve it.

I'm very skeptical that climate change can lead to extinction. Maybe civilizational collapse (I don't believe it will though), but there is no plausible path to extinction.
