I didn't say there was no such thing as pollution. I said the assertion that human-caused pollution is "killing the Earth" is nonsense. The Earth has been hit several times by comets and giant asteroids. It's been hit by a gamma ray burst. It's even seen climate change so drastic that the entire Earth was covered in ice.
The Earth is still here. It takes a lot to kill a biosphere. Humans are not enough. You think too highly of yourself.
Further, humanity is part of the biosphere. Had it not occurred to you that the biosphere evolved intelligence to protect itself? For all the long history of life on Earth, the biosphere could not protect itself from asteroid and comet impacts causing mass extinction events. Guess what? It can now. You are part of the biosphere, not some alien dropped on the Earth to pollute it to death. For the first time in the life of the Earth, the Earth can reach out and avert mass extinction.
The Earth can even spread itself to other worlds (reproduction).
Stop acting like you are separate from the Earth.
