Incase of the decrement of the living space in the arctic the different types of species that live there might have to immigrate. But not all of the habitats of the arctic are able to move to another continent, this is going to lead to extinction of many different species. Some types of species that are living in arctic are very precious to the world, for ea. Polar bears. The movement of animals to the other regions with different climate may cause a brake down in the food chains. There might be a failure in the trophic levels because some of the animals are going to be new to a particular environment. As the polar bears are not going to have the ice habitats as fish anymore so they wouldn’t be able to feed themselves.
