Yes. That is pointless.
Humans will do themselves in far before the planet will ever have a chance to rid this waste.
We will exterminate ourselves within 500 years. The US will probably be at the forefront claiming we're in danger of some made up threat, then other countries will join in. We'll probably blame a bearded guy in a cave again.
You must be right up on climate science, 500 years we will be starving and dying in a drought filled, empty ocean world.
The funny thing is humans do think they are the center of the universe, ie I will do what I can for mine etc.. fuck the planet we live on.
