Are there any animals that have a negative effect on the environment?

    Absolutely, though most of the time these animals are simply out of their home territory.  Such exotic animals that cause problems are known as invasive species.  Asian carp are one example.  They are ferocious eaters and can wipe out part of the food web in an ecosystem.

    When ecosystems are disrupted it can cause some animal populations to swell to huge numbers to the point of overpopulated areas. The white-tailed deer is a good example of this. In areas where the deer no longer have natural predators, they are able to clean out the food source in that area which not only affects them but other animals as well.
