You could quit doom scrolling and learn that the vast majority of everything is and WILL be fixed given a long enough timeline. Humanity has proven over and over that the vast majority of us are good people just wanting to live our lives happily. There are always great people doing great things behind the scenes that never generate as many clicks as OMG KILLINGS OMG THREATEN NUKES OMG OTHERS!
Lets start you off with the easy recommendation. Kurzgesagt Overpopulation and how it's bullshit:
I disagree that you should believe everything will be fixed given enough time. I don't believe doomerism is the correct response either, but I fear that believing things will just work out makes it easy to ignore problems.
Lol, I'm a Science+Tech nerd. I also watch Kurzgesagt and some other science and math related channels, like Sciencephile AI, Vsauce, Veritasium, 3brown1blue, Science Click and so on.
