In the show "3 Body Problem" (I haven't read the book) the statement was made 'our civilization is no longer capable of solving its own problems'. Would you agree?
Those were the delusional words of someone who lived in an upside down country. Kinda agree but if a single country fails, humanity doesn't get extinguished.
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?
Earth's climate has changed many times before and life found a way, regardless.
People who hate themselves and have low self steem say that humans are cancer but the real cancer are the doomers that only sigh, complain and lie flat without doing anything to help because they think everything is doomed. Well, aside from the usual corporate billionaire cancer from crapitalism
