The world's population has doubled since 1970, and there were people complaining about over population even then.
So any meaningful reduction in population would need to take us back to about that.
Now, I don't want to know what 3.7bn rotting corpses, or 3.7bn cremations would do to the world. but i;m guessing carbon emissions would go through the roof.
So really we need to send them all to another planet. If we build a big enough space craft we could get loads in, but we'd need to shuttle them out from Earth. Even aggressive plans mean no more than 300 people in a shuttle so we'd need 12million launches or thereabouts.
If we launched one every hour then it would still take 1,300 years and the emissions don't bear thinking about.
So I think we're screwed unless some invents a destructor ray gun.
