How Algal Blooms Affect The Environment

Algal blooms are thick layers of small green plants that appear on the surface of lakes and other water bodies due to excess nutrients, especially phosphorus and nitrogen.

The excess level of nutrients that algae depend on results from human activities that cause pollution, such as fertilizer, wastewater, manure, and sewage runoff.
