On depression rehab treatment centers

Funny, I used to read a lot of science fiction when I was a kid, but to the best of my memory, no author ever thought of the threat of space junk -- the pieces of destroyed satellites etc that are orbiting the Earth, and which threaten the safety of ships going up such as the shuttle. And, now, the space station where the shuttle is docked. I guess it's a symptom of the assumption that the universe is big enough to take all humanity's junk and just somehow get rid of it. That's pretty true for small time groups. It's less true for cities. And even less true when we're all over the planet. Yet people still dump stuff into the oceans and the other main waters. They seem big -- they are big -- but still cannot just dissolve all that stuff. Space is much bigger, but the debris is not headed out toward space, or falling into the sun, it's just orbiting the Earth. Someday we'll have to put some depression rehab treatment centers to treat people who are missing the Earth.
