Your views on environmentalism are interesting. Do you have data about most people being convinced "that no-one should be allowed to extend human life", or "that Malthus was right"? If we're going anecdote vs. anecdote, I really don't see what you're talking about - I hear very little about longevity or exponential population growth being the problem.
What you mention that I do hear a lot about is that resources are running out. This concept seems almost a tautology to me - if resources are finite, and we are using them without replacing them, then they are running out. This says nothing of how quickly they are running out, which is why people are doing lots of research on this problem.
Your point about incentives is actually exactly why the possibility of resource shortage frightens me more than nuclear war - the people of the world and their leaders are currently incentivized to trade off long-term resource scarcity for short-term economic growth, and there are currently many economies in need of growth.
