As someone already said, we should not worry about our planet, for it is going to be here, long long after we are finished. We should be worried about ourselves. We rely on our planet for our existence and the current state of our planet hangs on a fine balance of its constituent elements.
If we were to change the balance, the planet would not die, it would only enter into a new different state. But we would surely die or at least most of us would.
Some of us think that sooner or later, humans would be able to colonize other places in Universe and then our survival would not wholly rely on Earth. That is certainly possible. But how far into the future would that be possible and whether we would be able to survive another hundred years of drastic pollution of Earth is anyone's guess.
