The Consequences Of Eutrophication

1466 Words 6 Pages
Eutrophication is a natural occurrence over the past centuries as bodies of water age and contains sediment (Carpenter 1981). However, due to human activities, the rate of eutrophication has increased and now plays a big role in fish kills. This happens when inordinate amount of fertilizers flow down the rivers and streams and into the sea, which in turn encourages algae and most, if not all, aquatic plants to overgrow. Fishes will then suffocate due to lack of oxygen and sunlight excessively consumed by algae and aquatic plants. According to Dodds et al, cyanobacteria blooms, contaminated supplies of drinking water, and hypoxia are the known consequences of eutrophication. Chislock, M. F., Doster, E., Zitomer, R. A. & Wilson, A. E. (2013) quoted Lehtiniemi et al (2005), in their article: Eutrophication: Causes, Consequences, and Controls in Aquatic Ecosystems.
