Think about climate change and reevaluate that position. There is no feasible way that the countries of the world will get together and all agree to do anything meaningful about it because anything MEANINGFUL will result in mass death. There’s really no other way around it. Which is why everyone is dragging their feet. Who wants that? Who wants to be responsible for that?
I can give you the only true answer to your question of “what can I do today to help fight climate change?” But you won’t like it and this ‘solution’ does not preserve society in really any meaningful way, however it does help to address climate change and prevent the entire natural world from dying of heat stroke. So the question becomes, what do you want to save? You can’t save everything and trying to do so will only result in you saving nothing.
The answer is large scale industrial sabotage. And when everything grinds to a halt and people start starving to death because of no industrialized food production and various other factors, you will regret the actions. As you and your own family fall victim to violence over food or land because everyone is panicking and trying to survive, you will likely regret it more. But then in 1000 years, there may still be people alive to call you a monster, if they remember you at all.
Nearly every piece of legislature is tailored to the desires of the wealthy. Politicians ignore the cries of the public in favor of donors. If you want change, set things on fire. Preferably their and their donors houses.
I have lost all hope and am behaving as though we will all be dead within 25 years, and although that is not LITERALLY true, the actual reality is that billions will die in the coming decades and it won’t be peacefully in their sleep. The famines, wars and plain savagery will be awe inspiring to witness. The die offs of all life in the oceans and the insects will doom us to a swift death.
I exist and nothing more. I have no feelings one way or the other at this point. If I get hit by a car on my way home, it would be just as enjoyable as if I watched a good movie, although if I were to die in the crash, it might be a bit better than the movie.
I only hope that I can exact some form of vengeance on those responsible before we all perish.
