I think some people who read hacker news may be interested in discussions of the increasingly serious challenges facing us as individuals, communities, and as a species.

Compared to many people in the world, I suspect that those people reading hacker news may have a relatively large opportunity to influence others, for better or worse.

If we discuss these kinds of issues there is a small chance that some people will decide to act in a way that is more beneficial to others, society, & the environment.

It's backwards thinking, based on a moralization that mother nature is all good and human beings are all bad. If you look at all the problems associated with the "human overcrowding" problem, the solution is more knowledge, not less people. To stop overpopulation: educate and empower women. To slow carbon emissions: keep track and educate people about the consequences. You can join this particular doomsday cult if you so desire, as long as you don't try to prevent me from reproducing. I will still roll my eyes at you, but nothing more.

I like to take an interest in what other folks of a similar mind are involved in, even outside of programming/computers. There are more than a few (semi)well-known programmers who are actually involved in or otherwise support the VHEMT.

I enjoy them. I still can't tell if this one is real or intended as humor. That's fascinating to me.

Because they're interesting. And this is a place of interesting things.
