Eutrophication is bad for the environment. In fact, Naturvårdsverket classifies eutrophication as the greatest threat to the marine environment.
One of the major contributing causes of eutrophication is nitrogen oxide emissions from vehicle traffic.
The emissions of nitrogen oxides also acidify land and water, and harm our genome, airways and mucous membranes.
Together with hydrocarbons, nitrogen oxides also contribute to the formation of ground-level ozone.
