Deer eat leaves and things that grow in the forest, then they leave their feces behind. This adds to the fertility of the forest soil.
They are a part of it.
by running
they keep other populations of animals,such as caribou and deer, from exploding
They help keep a good number of grass eating animals like deer and rabbit.

KILLS DEER AND ELK to make shure there is nott too much graas because deer and elk are like living lawnmowers that almost never stop
Adaption to the Environment.
Deer are not "bad for the environment". Too many of anything, including deer, is bad, because it means they will probably be unable to find sufficient food and will end up starving. If a given plot of land can support 100 deer, and there are 200 deer in that area, probably more than 100 of them will starve, since the 100 "doomed" deer will eat some of the food, which is effectively wasted when they end up dying anyway.
If the wolf is wiped out from an area that would have animals like deer, then the deer population would raise rapidly.
An overpopulation of dear is a BAD thing it will hurt the deer and the environment. The only good thing is that some of the deer can be culled to reduce the population to sustainable levels and the culled deer make very good eating.
erosion can never help the environment indeed it affects environment
They can run fast from other attacking animals, and can hear them approaching. A deer's coat is the perfect camouflage, blending in to the forest or meadow. It's long neck helps it see it's predators from a distance. And its eyes can see in the dark.
The plural of deer is still deer with no S. Deer simply interact with their environment and because they do not hibernate, only react and don't plan ahead like a bear or groundhog does.
