It would kind of all be fucked by the fact that the pokeballs would probably cost around $200 a piece.
It would probably be some sort of super-hunting for the rich and famous, and the only way it could effect us is we'd have to bring shears to cut any long grass whenever we went out. The furries would be fucked, because bestiality involving pokemon would be made illegal, and they're probably be some mad scientist that tried to clone them and made some sort of mutation between a mudkip and a seaking. We'd start making battery moomoos, only to be fucked over by the 40 ratatas runing around in the barn. Food as we know it may well colapse, leving us starved and unable to prevent the upcoming poke-pocolipce.
... At least reality TV would be a bit more interesting, though.
