Star Trek predicted a lot of things we take for granted now — everything from tablet computers to cellphones. But this 1973 public service announcement, featuring the voices of the original cast, is one of the first depictions of the huge problem of space junk.
Star Trek: The Animated Series only ran from 1973-1974. But, that was enough time for Filmation to produce this brief message on behalf of the Keep America Beautiful campaign. Behold, the terrible tragedy that is the "Romvian Pollution Belt" — unlike the spaceship debris you sometimes see in science fiction in the wake of battles, this is just space junk left by the "Romvians" due to a lack of consciousness about pollution. The makers of this TV spot probably didn't know how ahead of their time they were.
