There are massive amounts of Pokemon hotter than the sun. they would sink through the ground into the earths core. Then many volcanoes would come up from the ground, causing massive devastation. The only safe would place would be the sea, but there are lots of danger from the Pokemon living there. Not to mention the food that people wouldn’t have because there is no agriculture.
If Pokemon were real, we wouldn’t be having this discussion because we wouldn’t be fantasizing about what it would be like if Pokemon were real. Also, there would be no merchandise, probably. We would see them as animals, probably, just as we see tigers, fish, dogs, and such. Finally, everyone would be outside looking for that Pikachu.
This very much depends on how this would come to be. If it was a sudden change, in which Pokemon and all related items and resources just came into being one day, it would be literal hell. Hundreds of different creatures many of which have the powers of gods just show up one day, and in doing what they normally do, we would suffer, as our world is not prepared for it. However, if it where to be that we all lived in the Pokemon universe, then that would be pretty cool. I feel like it would be a lot like it is portrayed in the games and show. Life would be interesting, getting to catch, train, and befriend wild animals, and use them to fight other people who are doing the same thing. The only real down side I can think of is that the wold could end at the drop of a hat, though there will probably be a 10 year old that just so happens to be in the right place at the right time and save the day.
Ummm, I am fairly certain there are quite a few organizations that exist in our world to prevent people from catching training and fighting animals… just saying.
