The world is pretty brutal. Evolution depends on death, economy depends on resources extracted from the ground, which is usually an unclean process.
We have at least managed to get the worst pollution out of our cities (nothing like London's Great Smog [0] is happening in the developed world anymore), and we can protect at least some natural parks, but it will realistically take at least a hundred more years of technological development until we can run an economy that does not damage the Earth anymore.
And that will likely mean mining of stuff elsewhere, such as the asteroid belt.
