Phosphates

Phosphates are a big problem in the world. They kill off fish, and cause Algal blooms. Phosphates are chemicals, often found in fertilizers, Phosphates are now getting into protected waters, and killing of endangered sea life. The phosphates are becoming one of the largest fish-consumed chemicals.  An Algal bloom is when phosphates leak into a body of water and the Algae decides to stock up on the nutrients in the phosphates, which are actually good for the Algae. The Algae takes up all of the oxygen and the fish and other inhabitants of the lake, stream, etc. die off from lack of air in the water. There is a limited amount of space for the Algae, so they soon die.
