My son is now 26 and I wonder if the environment will make it to the end of his life. I hope it does. And I hope, that lacking any substantive change in how humans behave, that he and his GF opt out of kids, because I'm certain they would live to see the world fall apart (probably not end in a literal sense, but it's going to get ugly).

I'm optimistic. I work in agriculture and so see all the advances coming - right now there is more than enough food to go around despite bad weather, and yields are still going up fast. In the mean time world population growth is slowing down as third world countries advance to the point where more babies is bad for the family.
