Ok, im getting pretty sick of you all bashing on luna for banning a few retards, so i'm going to explain why you are idiots :D
Let's say we pass a law that says we no longer can bury the waste in landfills, we can pretend that works for a while , but sooner or later the garbage will start overflowing, so unless we want to get buried by it, we have to get rid of some of it.
