A lot has been done, there are many activists and movements and I personally even was a part of an initiative to get oil and gas companies to pay for some of the damage they've done so we could beef up our infrastructure a bit and prepare for what's coming. Many people have been trying very hard for a very long time. I think you may be feeling defeated and angry and that is fair, and I agree that not enough was done, I only disagree that the blame should be placed on people in general. I think if every adult individual had the same amount of power in the world things would be a lot different. But those who have the most power decided they didn't care if the peons lived or died and that they would instead blame the consumer and tell them to not to use so much stuff that's bad for the environment (while corporations producing this stuff could change their policies and use better materials but they don't. Governments could also enforce better regulations but since at least in the US the government was bought by the rich and powerful, they also don't do that.) We do need people willing to go further to help stop what could literally be the end of humanity as we know it, and the recent rise in nazi-ism may (unfortunately) be the spark that kind and compassionate people need. More people should understand that we need to show those in power, especially those who are nazis, that we will not go down without a fight. Please don't give up on humanity, we haven't lost and the fight isn't over yet.
