How Human Activities Negatively Affect the Ecosystem Essay

In various ecosystems, proscribe pitchs consume been seen as consequences of humane activities. Specifically, these various activities of people have been observed to contribute directly and indirectly to the shun changes and subtractions in one of the major ecosystems, the maritime ecosystem. This paper suggests that many of the human activities employed in the milieu, specifically the ocean ecosystem, yield multiplicative detrimental do.It is said that humans have a high influence over ecosystems, and the various activities they make alter the environments conditions (Millennium Ecosystem Assessment, 2003). According to Hylland (2002), there ar many different perspectives that could depone the impact of human activities towards nature. However, in purely simplistic illustrations, human activities that demand physical disturbance, release of harmful chemicals, and other stilbesteroltructive forms cause undecomposed effects much(prenominal) as a reduced biodiversity. Physical disturbances such as trawling, large scale angle, or coastal construction keep back fish and other nautical species from staying in their original habitat. This means that these oceanic fauna are displaced from their habitat which may have been destroyed or changed beyond recovery by drastic seek activities made by man. Similarly, the oceanic ecosystem may non only be lessened because of the displaced marine organisms, but it is overly possible that an eventual decrease in the world level of these organisms may happen.This could trigger to a relatively damaging human activity wherein humans go away aim for the fish nearer the coastal areas. Under many legislation proceedings, fishing near the coastal areas is prohibit because the act will strip the number of fish and other marine species into a minimal number. Over-fishing could as well cause the decrease in the biodiversity of marine animals (Hylland, 2002). The use of chemicals in fishing could also destroy not only the marine species but also their habitat and where eventually, humans will also be affected.This is a chain-like series of events that could lead into a negative effect, destruction even, among marine biological ecosystems. Cyanide and other dynamite fishing are often used by fishermen as an easier method of fishing that kill even the smaller fish. If these methods continue, the marine species will no long-lasting be sustained. The chemical by products from these methods also destroy their natural ecosystem by contaminating changes that are harmful to the lives of these species.Similarly, there are instances where pollutants and toxic materials from pesticides go as water run-off from residential and agricultural areas toward the seas and other water forms, thereby contaminating the seas and the living organisms in it with the toxic substances (Hylland, 2002). Another major price reduction that is currently of relevance is the aftereffect of negative human activities that c haracterize an indirect implication climate change. Because of the ensuing pollution, forest denudation and other factors, climate change and global warming have been relatively causing damage.These have negative effects as well on the marine ecosystems as the seas are heating up, thereby changing the distribution of species (Hylland, 2002). Conclusively, it must be famous that many various human endeavors have multiplicative detrimental effects to many ecosystems, specifically the marine ecosystem. As mentioned, the negative effects do not only encompass the destruction of the marine ecosystems but also the biodiversity of the marine species. When the habitats are destroyed, the number of marine organisms decreases, therefore catapulting to unsustainability in the ecologic balance.This goes to show that every human activity that has negative impacts will be felt multiplicatively through direct and indirect measures.
