U.S. Forests May Be Products Of Pollution

Studies of pristine forests in South America found that the cycling of nitrogen, an essential nutrient, was quite different than expected, and it suggests that many forests of North America and Europe actually have an unnatural ecology driven largely by air pollution, acid rain and artificial nitrogen fertilization.
Does this mean it is now ok to cut down all these "unnatural" trees?
