all this talk about "saving the planet". the planet doesn't need saving, it can look after itself. when we're gone, it'll busy itself setting everything right, new life will emerge to fill the niches left by any mass extinctions we might cause, as has happened many times previously; that it may take hundreds of thousands of years is neither here nor there, it's a blink of an eye in the great scheme of things.
no, what needs saving is our lifestyle. the current one is unsustainable and if we don't make changes it will - if not now because of climate change, then later due to overpopulation or exhaustion of resources - result in our own demise.
