5 North American Animals Vs 5 European Animals - The Battle For Dominance Of An Ecosystem

The north American and European ecosystems are more similar than most people believe, with some aquatic, land, and airborne animals being found on both continents.
Some of these animals occur on both the north American and Eurasian landmasses naturally, but over the years there have also been quite a few invaders.
Because we humans have a destructive habit of introducing wild animals outside their native range, there are now north American animals that are thriving in Europe, and European animals that are living their new lives in north America.
In some cases the introduced animals face little competition and only have a few threats to worry about, but some non native animals need to fight for dominance of their new ecosystem.
In todays video I'll be taking a look at a few of these instances both in north America and Europe, and I'll be trying to work out which species has won, or if the battle has turned into a stalemate.
