Water Pollution

Water Pollution (specifically ammonia) final draft
My topic will be on water pollution. Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities. Although natural phenomena such as volcanoes, storms, earthquakes etc. also cause major changes in water quality and the ecological status of water, these are not deemed to be pollution. Organic wastes such as sewage and farm waste impose high oxygen demands on the receiving water leading to oxygen depletion with potentially severe impacts on the whole ecosystem.Silt-bearing runoff from many activities including construction sites, forestry and farms can inhibit the penetration of sunlight through the water column restricting photosynthesis and causing blanketing of the lake or river bed which in turns damages the ecology. I am gonna appeal my chime to people who do beach cleanups not because they are doing a bad job but because they have been doing a good job. I also want to appeal it to people who waste water and leave trash everywhere. I want everyone to know where the trash goes when they dump it or leave it anywhere, and what happens when it gets in the water.
