Has there ever been a time when it wasn't like that? That awareness, of the damage humanity does to itself and the planet, and is in fact by most measures a plague on it--and nature has ways of dealing with plagues--is a relatively recent phenomenon. I think you're probably living in the best time, at least so far, for someone like you. The only conceivably better time hasn't happened yet. Maybe you can help make it happen.
I think life would make more sense to you if you accepted that you had nothing to do with that choice, it wasn't yours. But as long as you're here now, you can choose what you're going to do with the time you have. As Christopher Hitchens observed shortly before his death, the conversation about what is true, what is good, what is right, what is beautiful, is really the only one worth having. So have that conversation with anyone who's also interested in it. Lamentably, a lot of people aren't, and I'm sure you know that a lot of people who are won't agree with you about what's true, good, etc.--in fact I'm one of them--but that's why such conversations are so important. There's no other way to make progress.
So go for it. I think you're one of the good guys, and you do make a difference.
