Elevated Carbon Dioxide Levels May Mitigate Losses of Biodiversity from Nitrogen Pollution

The levels of carbon dioxide are rising causing enviromental problems and over heating the planet, however according to a new study it believed that the rising CO2 levels may be counteracting losses of diversity from another enviromental issue, global rain of nitrogen from fertilizers and exhaust fumes. A ten year experiment involving open air and 48 plotted plants, 16 different species of plants. They tested the plants using ambient and elevated levels nitrogen and carbon dioxide. They measureed many things, plant biomass above and below ground and the number of species in each plot. Over time the diversity changed significantly depending on the amount of nitrogen and carbon dioxide.
