Explanation:
Taking steps to reduce or eliminate pollution from nonpoint sources such as streets and farms will help to maintain the ecological balance. Sewage and run-off of agricultural fertilizer can cause the rapid growth of algae in lakes and streams. The growth of algae blocks sunlight and depletes the oxygen in the water.
The reason why the electricity could decrease is because the population of the town’s people has gone down causing the electricity rate to decrease. Hope this helps you.
