What are some ways in which our political and economic system has inhibited the response to scientific information about the damage these phenomena have caused? Some examples you can look up are the Love Canal, Rachel Carson’s book Silent Spring, the burning of the Cuyahoga River, and the Exxon Valdez oil spill (but feel free to find your own as well). Remember also the climate change video from Dr. Oreskes available on the course pages. Explain at least 3 ways. (This is an environmental science question)

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
