What is water pollution and who cause water pollution? Water pollution It's a huge problems in earth, animals are the most effect when water is contaminated, but also water pollution affected humans health. Sometimes we don’t see but we are always contaminating water by throwing thrash and exposing chemicals on water. Humans are the reason why water pollution exist, but we can something about it to end water pollution. What is water pollution?
Two-thirds of the earth’s surface is made up of the water which forms such an important part of our lives. Despite this, we as the human race continue to pollute our water; risking the amount of water available to us and in turn causing unchangeable effects. Water pollution is a consequential change in the physical or chemical properties of water thus contaminating the water bodies. The quality of water is therefore at risk due to the many different types of water pollution. The most visible form of pollution is surface water pollution as we are able to see it floating in its physical form on the surface of lakes, streams, and oceans.
Eutrophication is an extreme wealth of supplements in a lake or different waterways. Eutrophication happens when the spillover of residue from and land go into a waterway. At the point when this happens, a thick development of vegetation happens, which exhausts the huge oxygen request (BOD), which means the oxygen that is accessible to amphibian life is no more. Eutrophication might likewise be realized by the seepage of sewage, mechanical squanders, or cleansers into a waterway. As the stuffed plants cease to exist, the dead and rotting vegetation exhausts the lake 's oxygen supply.
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
Water is a colorless, tasteless, and odorless chemical substance which is the main constituent of the Earth and also the living organisms. Water is crucial to our survival and is the life giver. We depend on water to live and no life exists without water. According to Ericsson and Steffen (2016), safe and efficient treatment of water has been among the major public health advances of the 20th century. Without it, waterborne diseases would spread rapidly in most public water systems and can be detrimental to our health.
Nutrients pollution, come from wastewater, fertilizer and sewage contain high level of nutrient. The nutrients encourage the growth of algae and weed which use up the oxygen and causes the living organism in water to be lack of oxygen and eventually causes death. Nutrient pollution has impacted many streams, rivers, lakes, bays and coastal waters for the past several decades, resulting in serious environmental and human health .issues, and impacting the economy. Algea growth in aquatic system can lead to damages of water quality, food resources and habitat. Since algae consume dissolved oxygen in water, this can cause depletion of dissolved oxygen that very crucial to fish and other aquatic creatures to survive.
Water is vital requirement of life but today whole world is facing water crises. These water crises are due to unrestricted and huge exploitation of water. Rapid urbanization of natural resources of water such as a huge increase in industries, especially textile industries have threat to water bodies. The discharge effluents from these industries have various harmful and toxic components mainly dye. This deteriorates water and makes it unsafe for further use.
“FLOW: For the Love of Water” Tragedy of a common resource no one can relinquish The award winning, 2008 documentary “Flow: For the Love of Water” presents a partisan piece of cinematography on a topic that until then had—for many living in the rich world—been taken for granted: clean drinking water. Following the long effective tactics of environmental shock doctrine, the movie makes a case for the pressing issues related to water shortage and wrongs within the water industry, especially the bottled water industry. After outlining the current threats global water supplies face, because of agricultural use and pollution for example, the movie moves on to what it deems the main culprit for the remaining water resources’ unfair distribution
Not so long ago, provisioning rural areas with deep tube wells were considered enough for water supply. But now we need to use distillation techniques to label the water as safe for drinking. The e-devices and batteries we casually throw away has resulted in poisoning groundwater by mixing it with lead and mercury. Thus, not only environmental and physical damage is caused due to these wastes, it leads to substantial increase in monetary cost for stakeholders like governments and industries. To address this, we need to first understand what e-wastes are.
Although the economy has been developing, the quality of water in Tianjin is decreased year by year. Because of water pollution is getting worse; I have to install a household water purification system, to ensure the domestic water could be used safely. Meanwhile, water must be boiled because this process can ensure the water is harmless to the body. Water pollution not only increased my living costs but also caused a waste of energy. According to the article from "Journal of Environmental Sciences", the concentration of nitrogen and phosphorus in the rivers of Tianjin has been severely exceeded, the concentrations of various metal ions had reached harmful degree to the human body, and the water quality of 56.6% rivers was worse than Grade V. This severe water pollution problem has severely affected the life of all Tianjin residents, including me.
