how human activity negatively affects many ecosystems throughout the world
(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 longer 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 implication that is currently of relevance is the aftereffect of negative human activities that characterize 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 noted 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 ecological balance . This goes to show that every human activity that has negative impacts will be felt multiplicatively through direct and indirect measures
