Most of the destruction is Capitalism and Consumer Society overproduction and overexploitation - a lot of unecessary shit is done and a lot of what’s done is done in unecessarily destructive ways (with lots of Negative Externatities) when it could’ve been done in far less destructive but less profit-generating ways, all because our political and economic structures are dedicated to the maximization of the wealth of the richest people.
(It’s not by chance that Ecologist parties are generally leftwing - the politicies for protecting the Environment are generally diametrally opposite of the politicies that maximize the investment profits of those who own most shit and have the most money)
I bet that only about 100 people need to die (all billionaires) to save the planet, an acceptable sacrifice.








The absence of their influence in Politics will make a massive difference.
The resources captured by the rich are probably a far smaller part of the problems they make than how they use the money they have to shape Politics and Public Opinion (via the Media they own), hence policies, hence the way our society and economy operates to maximized their own wealth.
Most Overconsumption and Negative Externality problems (both things that serve to maximized the profits that end up in the hands of Asset Owners and both the kind of thing that most damages the Environment) could be legislated away, but there is no will and there is no will because the politicians and the media are bought by those who benefit from things being as they are, and they are bought because those people have lots of money to buy them with.
Take the power to buy politicians and deciding what the press puts out away from the rich and all of a sudden profit-reducing pro-Environmental policies are not just politically acceptable but even demanded by public opinion, and given that said rich people would never give up on that without a massivelly destructive fight (literally Revolution), the safest and best option for about 99.9998% of people (8 billion minus 10,000 out of 8 billion) would probably be that a handful of rich people just die.
