Question

Quizplus · Accepted Answer

Lawn fertilizer is a major nonpoint source of nitrogen pollution in suburban areas, as excess fertilizer can easily run off lawns during rain and enter nearby waterways, causing harmful algal blooms and other adverse effects in aquatic ecosystems. Pet waste can also contribute to nitrogen pollution, but it is typically a smaller source compared to fertilizer use. Rain gardens, native plants, and green roofs can all help limit runoff and nitrogen pollution, but they are not significant sources of pollution themselves.
