Ah yes. The inevitable denial that mankind can do anything that will actually completely destroy the planet. I'm afraid that the problem is far worse than you believe and unless we take action to reverse the situation soon it will simply be too late.

There are lots of ways we can eradicate most life on earth. However, I prefer accurate statements in important discussions.
We are incapable, as a species, to literally destroy the planet.
We are full capable of wiping out 90% of life on earth, and if we don't do something more very soon, I suspect we will. And yes, it will take the ecosphere 10s of thousands, 100s of thousands, or even a million years to fully recover.
Our civilization is what is at stake.
Our ability to feed our population.
Our relative ease of life which gives many of us time to research, invent and innovate.
We have built up a huge civilization in a relatively stable and warm climate. And we are pushing it well beyond its limits. And once it adjusts to the huge amount of co2 we are pumping into the atmosphere, it will not be nearly as hospitable.
Starvation of many? Likely.
Increased weather disasters? Alreay here.
Dark ages? Certainly possible.
Destroy the earth? Hyperbole
