The line of what is an acceptable solution was arbitrarily drawn right above (below?) veganism. If our environmental issues are caused due to humans, then removing all (or many) humans would solve the issue better than veganism. Or a more "realistic" single biggest way: No more fossil fuels. At all. That's technically a single change. I think that would have a larger environmental impact.
