As one might've implied, it's a humongous world whith so much, an so much awful things, going on. If you try to process it all, you simply implode. So, of course (some/most/all of) those things that don't affect us (that) directly will be pushed aside. It is impossible to care about everything while still being able to function, let alone maintaining yourself or others. We as the world are facing probably the biggest challenges yet, for several reasons. First, almost all of them are long-term effects, which we as humans are pretty bad at estimating their impact. Second, a lot of what keeps this society and economy (barely) together has to be abandoned in order to effectively tackle those. For example, our democracies are actually quite undemocratic, even corrupt to varying degree. I don't say that the past was much better, or that there are complete better systems out there atm, but it is to the detriment of the people and coöperation between states. Third, it has to be done collectively, meaning that everyone has to give in, some more than others. This includes having to give up part of one nation's sovereignity, which tends to be disliked by most politicians and people (especially people directly influenced by those politicians). We have to accept that we can't divide ourselves in little corners for everyone each. However, it is hard to accept giving up such rights if there's hardly any certainty that decisions made by such overruling bodies will be neutral and for the best of everyone. As long as that isn't solved, it is perfectly understandable that governments don't want to give up sovereignity to those bodies. Fourth (related to second), we don't have real solutions to some of those problems. We don't have a new economic model in the shelf if this one meets its demise, for one. A lot of the problems are really compplex, so solving them is one cluttery mess, which takes even more effort, if it would even help. Some things might never even have a good answer to them. Fifth, THERE'S SO MANY OF THEM. It's practically impossible for one to keep all those problems in mind. There are a lot of things going on at the same time, and as the number of them rises, our sensitivity to them dulls. Tackling them all would take huge sacrifices, and no-one is really eager to take those. I don't claim to have the answer for them all, but one can contribute to them, even if it's just a little, so that we can give our children (if you choose), or anyone after us, a better future.
