>Life will absolutely not go on if we don't start handling it.

Hyperbole much? The Earth used to be a molten rock and from it life sprung forth. Do you honestly believe that we can put it into a worse position?

Humans might go extinct, but I'm certain that life will go on.

The biosphere is not undestroyable by any measure. Prior extinction events haven't manage to permanently damage it, but we shouldn't set the bar that low and rely on life's magical ability to spring forth and prosper under any circumstances.
