This sounds rather short sighted to me. Changing our diet towards lower meat consumption (like we had 50 years ago - max. 1 portion of meat per week), has been shown to come with substantial health benefits. It is a no brainer that we should go there. Because the alternative is so much more detrimental for the human race. Being struck by climate change means we would have around 500 million people who need to migrate, besides other catastrophic effects.
