Didn't your mother tell you to clean up your trash? Well, it looks like those responsible for launches of satellites have forgotton those simple rules. Now the space station may have to duck orbiting debris since there is so much trash in orbit.
If you sawa Wall-e, you'll get a very clear picture of the future of low earth orbit, its not that bad yet but there is a lot of stuff up there. The problem is that such a huge area is invovled that its almost impossible to imagine how to clean up the trash once its there. So hopefully mission planners are being more careful now than they used to be in order to avoid leaving dangerous material in orbit.
