I turn off the lights when I leave a room. I'm conscientious about my water usage. I recycle.
When I find that a company is a mass polluter, I do everything in my power to not give them any of my money.
I'm doing my part.
The fact is every human being on the planet in their own personal circle could go carbon neutral and climate change would still happen because it is industrial processes and commercial shipping that are driving the great majority of carbon and methane release in the atmosphere.
It's not anything that you or I are doing, or rather, in the scheme of things what we are doing is negligible, easily absorbed by the natural cleaning processes of the planet like trees and algae and rain and time.
Our current system has incentivized pollution. There's no amount of personal choice that we as individuals can take to stop it.
What we need are politicians who acknowledge the issue and who override the objections of the vocal minority to fix them even at deleterious costs to the economy.
After all, can't have an economy when the world is dead.
