Mans Effect On The Environment Essay

     Hazardous wastes are another problem for the water in our world. These wastes are toxic, reactive, corrosive or ignitable. Most problems come from humans not storing the substance properly or not disposing of it correctly. This can be easily proven in 1969, when the Cuyahoga River, in Cleveland, Ohio, caught on fire and burned for sometime. Since this happened environmentalists have taken extreme measures to reduce the amount of pollution that is coming out of the power plants that are on the river and on Lake Erie.

The polluted water supply that results can become harmful to humans. Aquatic life quickly suffers the effects of watershed pollution.

Let me go all APES here. Water contamination has been an issue across the country. Nutrients like phosphorous, which are found in many fertilizers, can runoff into streams and rivers causing eutrophication. Eutrophication is just a fancy word for these organic nutrients causing a reduction in dissolved oxygen in

Another way that water can be polluted is with chemicals from factories. Factories use water from streams, river, and lakes to power and cool off their machinery. This used water contains many chemicals from the factory processes that are released back into the normal water (Lenntech, 1988-2016). This released water is also warmer, causing the whole body of water to heat up. This causes lower oxygen levels, which can disturb the organisms living in the water (Lenntech, 1988-2016).

After taking samples, and running tests on the water of the U-Creek, the conclusion was made that the water quality of the U-Creek is excellent. Water quality is not excellent in all cases, but keeping good water quality is very important for life of the organisms in the water. One way that humans could change the water quality, or pollute the water is through runoff. Rivers are a very convenient place for the companies or farms to get rid of waste. For example, farmers put pesticides and fertilizers on their crops to protect them from bugs, or to help them grow better. Fertilizers contain nitrates and phosphates, if large amounts of these two things end up in the water it will lead to an overgrowth of plant life, and algae growth. Over time as the algae starts to rapidly grow, the algae will start to use up all of the dissolved oxygen in the water. Dissolved oxygen is very important to organism life so if it is all gone then organisms will start to die. Another way that humans pollute water is through chemical water deposits. Chemical waste is discharged from industrial processes, that can end up in rivers or streams. An example of a

Livestock and pets can also be affected by skin contact or swallowing harmful algae and some algae can be lethal to fish either as a result of the release

With all if the pollution, fish die. The pollution can cause no oxygen in the deeper part of the lake for animals. Studies show that in the late summers, parts of the lake do not have oxygen for animals in the deeper parts. From that, animals

Water Pollution has been an increasing problem over the last few years. Pollution comes from many different things; agricultural, urban runoff, industrial, sedimentary, animal wastes, and leeching from landfills/septic systems just to name a few (Resources). The reason why pollution has increased over the years is because the rise in population and the advancements in technology the society has made. If society plans on having their resources here for many years to come they are going to have to make some drastic changes in the way they treat the earth, and these changes will have to start with their pollutants (Foundation).

According Oraclethinkquest, "Water pollution has the potential to have a harmful effect on all living things including plants and animal species. Chemicals, radioactive waste, industrial waste in the water can affect species and their development. There is no

Pollution threatens our marine resources as well. Pollutants are released into the ocean as a

Scientists are concerned that the runoff from excess potting soil combined with lower-than-normal river flow has caused toxic blue algae to appear in North Coast Rivers over the last decade. The bacteria pose a risk to swimmers and kills aquatic invertebrates that salmon and trout eat. Officials have had to warn residents and their pets to stay away from the rivers. So far, 11 dogs have died from the bacteria since

Eutrophication is the slow process that occurs naturally in aquatic ecosystems, such as lakes and ponds. It is a result of an aging body of water gradually increasing its concentration of nutrients. This happens because the intervaling death and growth of organisms that, for whatever given reason, don’t cancel each other out, and modify the fertility of the ecosystem. Eutrophication is not inherently bad, but the hastening of this process through artificial means can be very harmful to the ecosystem, and ultimately end in failure.

abundant rainfall and flooding cause overflows from the sewage plants, which can get into freshwater sources

The largest source of contamination is runoff from land. Toxic runoff can be sewage, rainwater flowing over exposed topsoil, flooding or agricultural runoff. Rain can cause runoff of chemicals or waste that can seep into creeks, rivers and other waterways that lead to the ocean. Some of the chemicals found could be antibiotics or waste from animals, pesticides from crops or from pollutants, originating in the air, which have settled on land and washed away. Unless a solution to pollution runoff is found, this type of contamination will continue indefinitely and contribute to the deterioration of the ecosystem in the

Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds.
