Within heavily populated cities, such as those in China, even the smallest of activities could lead to hugely negative effects for the local water bodies. Even with relatively low ecological footprints per capita, the shear volume of citizens could offset that and result in poor environmental outlooks. This is because a large population calls for increases to industry and agriculture, which contribute to water pollution individually (Shao et al., 2006). Industrialization introduces so many chemicals into the waters, and the fertilizer and pesticides used in industrial farming also greatly pollutes water. Such activities have created a reality where toxicants are now mainly absorbed directly from food because of the heavy contamination of water sources, such as lakes and fresh water bodies.
Organic effluents such as domestic sewages are a serious problem and the discharge of small quantities of sewages into the aquatic systems can actually increase the productivity of ecosystems, however, excessive quantities will deplete oxygen content, causing severe threat to aquatic life. As a result, the presence of organic and inorganic pollutants in aquatic system continues to be one of the most important environmental issues of the world
First of all, the first cause of water pollution is sewage water. Sewage refers to liquid wastes containing a mixture of human feces and wastewater from non-industrial human activities such as bathing, washing, and cleaning. In many poor areas of the world, sewage is dumped into local waterways, in the absence of practical alternatives. Untreated sewage poses a major risk to human health since it
That whole elaboration on my part was a segway into some of the downsides associated with Hydropower. One major drawback is the disruptive nature hydropower has in regards to natural habitats. Specifically, aquatic ecosystems that reside in rivers and streams can be severely altered by the presence of hydropower plants. Fish or other aquatic animals may accidentally get caught in the turbines, resulting in death. This also has the potential to block migration and mating patterns, which would lead to a decrease in the population of certain species (“Various Disadvantages of Hydropower,” conserve-energy-future.com).
Moreover, river pollution has become one of serious issues in last few years. Rivers is one of the main source of clean water. Water is the most important natural resource for life. Furthermore, human being needs water not only for drinking but also for cooking, washing, irrigation and fishing. People have been abusing and misusing water since long.
“Any change or modification in the physical, chemical and biological properties of water that will have a detrimental consequence on living things is water pollution.” Water pollution affects the drinking water, lakes, rivers and all over the world. In many developing countries, the polluted water leads to death. Figure 4: Ways of polluting water Types of Water Pollution Water pollution has many types some are discussed in this section: 1. Nutrient
The sewage water would mix with the pipelines and thus, it would pollute the water of the agriculture and the drinking water. Moreover, the pollution of water would lead to the poor health of the people. The people would suffer from toxicity and the water pollution would lead to the increase of the mortality rate in children. The water pollution is a very threatening problem and thus ,the society ahs to start to act accordingly to address this problem. (AUC, 2011) The Nile river is one of the most important and crucial sources of life in Egypt.
Water is a necessity for all life on Earth, yet it is one of the most threatened vital resources in the world. “Water pollution is any contamination of water with chemicals or other foreign substances” (Water Pollution). From automobile fluids that seep into sewage systems to household products that are usually poured down sinks, all these items can contribute to the destruction of the environment. However, these items have a common denominator: humans. Not enough people are aware of the dangerous effects that water pollution has towards the environment and what causes it.
Water is a crucial source used in many aspects of life. All around the world, water is becoming more and more scarce and the water available is being further contaminated by pollutants which come in a variety of forms, including organic, inorganic and radioactive that will lead to sickness and death of living organisms. Countries are experiencing droughts affecting the water supply needed to balance the ecosystem. Water pollution is a threat to human civilization and should be a global issue prevented by all countries. Therefore, many causes alongside their severe effects can be a list out regarding this issue.
Although most of the earth's surface is covered with water, water shortage is a serious threat to the survival of humanity at present and in future. There is a water crisis which faces many parts of the world and it is a threat to survival of human beings since humans are primarily dependent on water. Shortage in drinking water is a major problem facing developing countries which have not taken drastic steps to harvest water and purify it to make it safe for human consumption. However, this problem is also being increasingly felt in developed countries where the population growth has strained available water resources and stretched the ability of governments and private firms to provide safe drinking water to the population. There are many conflicts around the world where people have died or have been injured as a result of clashes over a water resource.
