Pollution question is not the same as 'running out of energy' question. You are just trying to save face now.
Uranium fission leaves us with radioactive waste.
Breeder reactors leave less waste by
an order of magnitude.
We need energy. We don't have enough energy coming into our system, so we tap into the supplies stored away over billions of years. Smart eh? Sustainable -- no.
it doesn't have to be. It only needs to last us long enough to get fusion power to go on-line.
In theory we could burn all plants and animals on earth and harvest energy. We could push the amount of energy we harvest to the limit. However in pushing this equilibrium to one side we are offsetting the natural cycles that constantly shift carbon, nitrogen, oxygen, etc, and are essential to life. If we pushed this equilibrium too far it would snap and we would have a nice little Easter Island the second on a much larger scale.
Again, do you have
any evidence for this?
Emitting extra CO2, if anything, will actually benefit plant life, by both providing plants with extra carbon extractable from the atmosphere, and by shifting the plant growth regions northward. Your catastrophic Easter island scenario is nowhere near being supported by any evidence. Realistic Global Warming scenarios point at damage to human civilization,
not at the collapse of the biosphere.
Natural "disasters", viruses, sickness, starvation, etc, etc -- all ways that the environment tries to limit a population.
Environment
tries? Wow, you ascribe intentionality to the ecosystem. Have you tried chatting with the environment over tea and some crumpets? You might be able to settle it amicably...
Perhaps my initial comment was dumb. We have TONS of oxygen in the atmosphere, oxygen depletion is probably the last way we would die out, I just wasn't thinking properly.
No, you weren't. Your thinking now is better, but only marginally so. You are still looking at imaginary dangers, and not dealign with reality.
