Well for one thing it's alot different, human and aliens live together. 99 percent of us in peace. My last roomate before I ended up here was an alien named Piggy. In 2001 Oh shit thats next yeathe Troobians attacked Earth. So they had to come live with us or be enslaved in their worlds. Or destroyed. For the ones that don't fit theirs S.P.D. Space Patrol Delta that takes care of domestic disturbances. We're Earth's last line of defense.
