Corporations consume most of our resources, produce the most waste, and damage _everything_ more compared to any individual. This won't change, because those with the power to do something benefit from the status quo and don't feel the damage they cause. Capitalism is a cancer that will consume everything.
Humans are to blame, not some mythical piece of paper granting limited liability.
Greed is the root of every evil on Earth.
What is greed?
Greed, is self over all else. Self over others. Self over environment. Self over all other considerations.
Greed is what is killing, has killed, and will continue to kill this planet and its populace.
You aren't in traffic, you are traffic.
You do not need to be greedy to contribute to a system built on greed. Being born into that system, forced to contribute to it at the penalty of starvation and death and taught and raised not to question or even comprehend the system is enough.
I'd recommend reading Debt: The First 5,000 Years by David Graeber if you want to understand how debt, money and states interconnect. I'm not saying you can't have money without states, I'm saying states are mechanisms to grant and enforce monopolies (i.e. exclusive access to and control of resources). If you want to maintain these systems without states, you'd end up with something resembling feudalism, which is just a more direct way to enforce property claims through violence.
Not sure the history of North Korea, China, Soviet Union, etc is an environmentalist paradise.
