Take a look at the Cargill family, 14 billionaires. From the wiki about the current CEO:
In 2019, former U.S. Congressman Henry A. Waxman, in a report by Mighty Earth, called Cargill "the worst company in the world" and noted that it drives "the most important problems facing our world" (deforestation, pollution, climate change, exploitation) "at a scale that dwarfs their closest competitors."
Do you think that is because they use every cent to burn coal and oil in their backyard, or
do you think it is because they produce and sell products to consumers which can not be produced without harm to the environment?
99% of the planet could produce zero pollution for the rest of our lives and it wouldn’t even make a dent in the amount of pollution created by the billionaire class.
How do you think they would create that damage to the environment if nobody would buy their products?
And no, I don't belive 100% tommorow is the only way to avoid that, that was your wording. But it has to and will change.
