The End of Space
Trash isn't just a problem on the surface of Earth — it also poses a danger for the communications and scientific infrastructure that we rely on in space. 60 years of launching things into orbit have created a huge amount of space junk that can destroy satellites, even at sizes as small as a pea. With the problem of space junk growing exponentially, some novel solutions have been proposed, from nets and harpoons to repelling magnets and lasers.
