CMV: I think that in the end, humanity will grow to become a prosperous eternally happy bunch & that every person can do something to help today.

If you look at history, it's very clear that stuff is getting better- only 100 years ago, there were no *proper* democracies & medicine was extremely unadvanced. 

Nowadays, we have all this amazing technology & medicine & a rapidly growing list of new democracies.

It seems that by each century in history you go forward so far, thing get way better. I think this trend will continue. 

**I know someone is going to mention about global warming/overpopulation,** but I do genuinely believe that will will come up with solutions to all of this, many of which are already in the pipeline. So many people seem to have a doom and gloom view of how the world is getting much worse. To me, this just seems like a contradiction in history.

I think anyone can help by being nice to others, and also by donating money to whatever cause, even if it's technological development. Perhaps I'm overly optimistic, but then again, perhaps I'm not.

I will address a couple of assumptions here that you may want to reconsider:

1) You suggest that history is one steady progression towards a better and better society. By and large that has been true for very recent history, but much of human history is the story of great societies being destroyed and regressing. At the height of the Roman Empire, much of Europe had stability, plumbing and clean water, a healthy economy, infrastructure. Those luxuries were not guaranteed, they were destroyed and didn't come back for a long time. In the Middle Ages, the Islamic world was very advanced - they had science, trade, and many other things. Then the Mongols came and burned it all down, killing millions of people along the way. You could argue that the region has never recovered. History shows that it is anything but "very clear that stuff is getting better."

2) Just because something can happen does not mean that it definitely will happen. We can address climate change, overpopulation, and other problems, but only if we take them seriously and treat it as a real threat. If everyone had the attitude of "everything will turn out fine, just relax", then we would never find the motivation to solve these problems. Hard societal problems can only be solved if we face the reality that we *need* to solve them or else we're doomed.
