This along with the algae blooms that remove large amounts of oxygen from the water have had a negative impact of the life of the fish and other life within the lake.
Discuss two polluted water bodies in your state, and discuss the steps that the state is taking to solve, prevent or reduce more pollution into these water bodies.
