Question

Quizplus · Accepted Answer

Nitrogen enrichment of ecosystems by human activity is largely driven by both addition of nitrogen fertilizers and nitrogen pollution from burning of fossil fuels. Both sources contribute to increased levels of nitrogen in the environment, which can lead to negative impacts on ecosystems such as eutrophication and harmful algal blooms. While nitrogen fixation by bacteria in landfills may contribute to nitrogen enrichment, it is not a major driver compared to fertilizer use and fossil fuel emissions.
