We did manage to change some things for the better - acid rain, ozone depletion, lead in everything. However with conflicting information and some corporations doing everything they can to muddy the consensus, it is hard to do the right thing. It is especially difficult if for years you think you’ve been doing the right thing and find out it was all fake - recycling.
It isn’t too late now. Apparently AI is a good target - eating a world’s supply of electricity to further enrich the billionaires while continuing to muddy the science of climate change. Wish people were as upset about that as they are about their porn being restricted.
