What impact do humans have on aquatic life zones?
Human’s desire to live near the coast has aided to the degradation of aquatic life zones. Today, around two-thirds of the worlds’ population lives near coasts. People have been drying wetlands and other coastal areas, in order to gain land for urban development. Most water bodies are now severely polluted, because we have been discharging wastewater in it for a very long time, before we realised this was very bad for the water quality. Coastal life zones are particularly sensitive to toxic contamination, because they are a dump for pesticides, heavy metals and other pollutants, which will soon accumulate to high levels. Run-off from sewage treatment plants and other water treatment systems is threatening all aquatic life zones nowadays and we are trying very hard to solve this problem. A human activity that seriously threats life in aquatic life zones is fishing. People do not know where to stop, so over fishing has become a common problem in oceans, as well as in inland waters.
