It was fun to read your explanation. However it is a bit paranoid thinking for me. It is like you would decide not to shower to keep yourself clean because anytime a carriage of excrement can fall into your neck so it don't worth the effort. Yep, man has screwed lots of stuff up, and will undo all of them, our and the forthcoming generation have the chance to do so. So don't be afraid -not even from sustainable designs (it is far better business to humankind than oil industry)-, things will be solved just strive on, and have faith.
