Mott Haven which is 1.181 mi² have been primarily a residential neighborhood in the southwestern section of the Bronx borough in New York City. Zip codes include 10451, 10454, and 10455. This site includes various things such as provisioning services, regulating services, cultural services, and supporting services. This site is also full of water sources, natural gases, and very biodiverse which are being polluted by human activities. Pollution can be physical chemical or biological and can affect water air or soil. Because of this, Mott Haven’s waterways is being affected by both these ways.With development, people tend to forget to take care of their environment. For instance, eutrophication people discard chemical waste in water which …show more content…
We have seen the many ways natural causes have impacted the environment. For example, when dust storms occur, particles and nutrients are being picked up and moved to other areas. This may lead to erosion and also to dissertation. Natural gases impact the environment from point to nonpoint sources. Point sources are defined by any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack. A nonpoint source pollution is when the source of the pollution is discrete such as the smoke cars produce which is very harmful to the environment. As a response to this, the United States Environmental Protection Agency (EPA) has created the Clean Air Act of 1990 which strengthens the regulations pertaining air quality standards. They have set a criteria of pollutants. Carbon monoxide, sulfur dioxide, nitrogen dioxide, tropospheric ozone, particulate matter, and lead pose especially great threats to human health. For these, the EPA has established National Ambient Air Quality Standards(NAAQS) which are the maximum allowed concentrations of these pollutants in ambient outdoors. The burning of fossil fuels cause industrial fog and grey air smog. The unburned remains are released as soot or particles of carbon which contains varying amounts of contaminants, including mercury and sulfur. This implements that natural gases have ways of polluting the …show more content…
According to ... extinction occurs when the last member of a species dies and the species cease to exist. This comes as a result from extirpation which is when a species cease to exist in a certain part of the world but not globally. Extinction is a natural process. The earth has experienced five mass extinction episodes. The first event was the Ordovician which was 400 million years ago with an unknown cause. This event affected marine organisms, and depleted more than 20% of families.. The next event was the Devonian which was 370 millions ago with an unknown cause, also affected marine organisms, and depleted more than 20% of families. Later on, the permo-Triassic event occurred 250 million years ago with a possible volcanic cause, and destroyed more than 50% of families, and 80-95% of species. The next event was called the End-Triassic event 202 million years ago and killed 20% of families and 50% of genera. The fifth event was the Cretaceous-Tertiary 65 million years ago, which was caused by asteroid impact and killed of 15% of families and 50% of species, including dinosaurs. Scientists are saying that the earth is currently experiencing a sixth extinction caused by human impacts and this affects large animals, specialized organisms, island organisms, and organisms harvested by people. This shows that biodiversity is being threatened by human activities.
