Water pollution: The Effect on human health:
In 21st century, humanity is facing a major challenge of a water quality issue. The main group includes aquatic contaminants and their effects on human health. Approach to improve pollution of fresh water resources.
Many of the major problems that are related to water quality and water quantity issues are facing by humanity in the twenty-first century
1) These problems are to be more provoked in the future by changing climate that results in higher water temperatures, melting of glaciers, and an strengthening of the water cycle
2) With more floods and droughts
3) With respect to human health, the most direct and most rigorous impact is the lack of improved cleanliness, and related to it is the lack

Because numerous reviews have appeared recently that cover the various aspects of waterborne diseases in a inclusive way. More eminence is placed on chemical pollution. More than one-third of Earth’s existing renewable freshwater is consumptively used for agricultural, industrial, and domestic purposes
5) As most of these activities lead to water contamination with diverse synthetic and geogenic natural chemicals, it comes as no surprise that chemical pollution of natural water has become a major public concern in almost all parts of the world. In fact, a recent Gallup poll taken in 2009 revealed that pollution of drinking water is the primary U.S. environmental concern.
6) Chemical water pollutants can be divided into two categories, the relatively small number of macropollutants, which typically occur at the milligram per liter level and include nutrients such as nitrogen
7) and phosphorous species
8) as well as natural organic

They include the following:
Waterborne Diseases: Waterborne diseases are arise from the contamination of water by human and animal body excretions infected by pathogenic viruses or bacteria, They are directly transmitted when the water is consumed or used for food preparations. Examples of waterborne diseases include cholera, typhoid, and cryptosporidiosis.
Water-deprivation Diseases: Water-Privation diseases which are affected by the quantity of water. The disease is spread through infected person contact or through contact with infected materials. Poor personal hygiene is a common factor leading to water-privation diseases.
Diseases Based on Water: In water-based diseases, water provides the habitat for intermediate host organisms in which parasites are able to pass part of their life cycle and later their infective larval forms in water are passed on the humans.
Diseases Related to water: In water-related diseases in which water provides a home for insects. Examples of these types of diseases include malaria, dengue and yellow
Disease caused by pollution might be caused by water pollution or air pollution, this is when the environment around a person is dirty. Examples are: Rickets, anemia,
When concerning our drinking water it should be considered that pathogenic organisms may contaminate soil, as well as stick on to the sediments in the surrounding area; making it more tricky to clear completely. Nitrate poisoning is another large concern,
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
The serious threat to the health of the IRL is the reduced water quality due to the manmade hydrologic changes, non-point pollution, loss
Lake Erie has been a huge topic for Ohioans due to how polluted the water is. Lake Erie is Ohio's biggest water source, and that being polluted is not good for Ohio and other states that use Lake Erie’s water. Though this is not the first time this has happened before, in 1960 the lake was VERY polluted due to heavy industries lined up on the shore lines. Lake Erie called the “Dead Lake” for how much pollution was in it, and how many dead fish there were.
All of our cells, organs and tissues depend on water to help regulate homeostasis. Homeostasis is when our cells seek and maintain a condition of equilibrium or stability internally as it deals with environmental external changes. Because water plays many important roles in the overall maintenance of the body, some of the functions of it include: regulates body temperature, carries nutrients and oxygen to cells, lubricates joints, helps dissolve minerals and other nutrients , and most importantly it also moistens tissues like the mouth, eyes and nose. Dehydration is when the body is deficient in water. Because the water in our bloodstream plays an important role in equally transporting cells and minerals throughout the body, when an individual is not getting enough water the cells in the body will begin to shrivel up and malfunction.
People complain about pollution from factories, cars, global warming, and the melting of polar ice caps, yet many people disregard the dangerous that come with fracking. Fracking is the process of injecting liquid at high pressure into subterranean rocks, and/or boreholes to force open existing fissures and extract oil or gas. Fracking is causing an epidemic economically and environmentally. Fracking is continuously destroying the earth day by day. From the endless fracking today’s economy is depleting.
Argumentative Essay Zeena Morar 12J Climate change is currently being felt around the world and unless the developed world makes substantial changes to its selfish ways, we are all doomed to face the fires of hell on earth. One third of the earth’s land is currently threatened as what we do to the air, land and water affects the balance of ecosystems and ultimately the world. The developed world uses wood for mining, building, furniture and paper. Saw and paper mills that are used to create these products, pollute the air and water.
Topic: Water Shortage Specific Purpose: To inform the audience about water shortage and how to cope with water scarcity Thesis Statement: Across the globe, reports reveal huge areas in crisis as reservoirs and aquifers dry up. I. INTRODUCTION A. Turning off the water while brushing their teeth, a family could save about 5 to 10 gallons of water per day. B. Freshwater shortage will cause the next great global crisis.
This essay will therefore critically discuss water scarcity and how one can prevent a war fought over water, as well as how one can save water and implement change to better our future nationally and globally. 2. The Importance of Water With two thirds of the earth 's surface covered by water and the human body consisting of 75 percent of it, it is clear that water is one of the core elements responsible for life on earth (Anderson, 1986). Water is very important to us because human bodies, as well as animals, cannot function without water in their systems.
One of the greatest issues that we face towards the environment has been an increasingly difficult problem over the last few years. Earths climate is changing at rapid paces and solutions are needed as quickly as possible to replenish natural ecosystems and cultures that depend on the environment. Climate change not only affects the animals in our ecosystem, but us humans as well. With the human population increasing every year, climate change is only getting worse. Many argue that the effects of climate change towards the environment are due to other extraneous factors, however, I myself am a strong believer that the problems such as rising sea levels, warmer temperatures and natural disasters are all due to both natural causes and human activity.
Water pollution is a serious issue as not only is water the most precious natural resource, but all sources of water support life that is very necessary for the survival of the planet. Water pollution destroys life and ecology and such damage is irreparable. Those who are still not serious about water pollution must also remember that the pollutants present in water not only destroy the life in the rivers and oceans, but also affect our food chain. Many people have the wrong notion that since they are not disposing the pollutants in the water they are not to blame. These people forget that 70% of the earth is covered by water, and any activity on the land can wash to the seas and oceans.
LITERATURE REVIEW What is water pollution? As the country is becoming more and more populated, the demands for social services have increased significantly. This has led to an increase of the pollution in many developing towns such as Ga-kgapane. The most disturbing and problematic forms of pollution in Ga-kgapane is the pollution of the natural streams. Water pollution is when there is a build of one or more substances in water to such an extent that it causes problems for animals or plants.
Directly or indirectly water has an effect on all the life forms inhabiting Earth. Vegetation is impossible without water, as we know plants need water for replenishment. On the same hand, both animals and humans also drink water, which is a major need of their bodies, without water they will loss normal functioning of body cells as boy cells require water, also its deficiency leaves the body dehydrated. Shortage or loss of water is a major threat to life sustainability on planet earth.
Water is the most important component found on the surface of the earth because it is source of life for living creatures. However, water pollution has become a global concern. Water pollution can have several forms from diverse sources. It is expected that there will be a lack of clean water in next few decades due to pollution. Nile river water in Egypt is the focus of attention of many studies due to many reasons.
