• In excess levels, nutrients over stimulate the growth of aquatic plants and algae.
• When the sediments various bodies of water, fish and other marine life respiration becomes impaired.
• Excessive growth of these types of organisms consequently clogs our waterways, use up dissolved oxygen as they decompose, and block light to deeper waters.
• Many fish or other marine life cannot survive when oxygen levels drop below two to five parts per million.
Cause
1. Factories throw their waste in water bodies
2. People bath and wash cloth in water bodies
