Do you have a source for that vegans think nothing else needs to change?
Nope.
This is more a comment about their priorities and the absolute futility of their tactics and goal.
Apparently you don't know the first thing about vegans.
First of all there are nearly 100 million vegans nowadays. They are not all the same. Second of all veganism isn't even about climate change, it's an ethical position towards the mistreatment of animals. Lastly, most vegans don't deny evolution or our history, but simply look at the situation that we find ourselves in today. Mass slaughtering 80+ billion land animals in factory farms annually may indeed be the result of our evolution, but evolution isn't finished either.
