I'm surprised women haven't been banned yet. They are by far the most wasteful sex. I used to empty my indoor garbage bin once every 2 weeks, but then I got a female roommate and had to empty it every single day. That's a 14x increase in consumption and waste!
Also, we should ban men because they start wars, and those are very wasteful, possibly more so than women... but many innovations have been a direct result of military spending. Now I'm back on the fence about who to ban, or what benefit has been provided
