Most of the water on the surface of the earth is sea water which is not usable for most of water’s essential purposes, including drinking. Fresh water is the most essential form of water for survival of life. The events of past years have raised the concern over the perennial availability of fresh water and are slowly converting fresh water into a commodity rather than an available for all resource. Preservation of the quality and availability of fresh water has become one of the most pressing environmental challenges in the 21st century. This concern is very high for third world countries where there is an alarmingly high dearth of drinkable water, rendering scores of people to die due to diseases emanating from poisonous water. Pressures on water resources: The increasing stress on water resources is from several sources and can take various forms. The impact of these pressures can vary and contribute to the ever increasing problem of easily available fresh water. Several factors contribute to increasing the stress on water resources. The growth of urban metropolises and changing lifestyles impacts the amount and pattern of water consumption. From using fresh water solely for necessary purposes, consumption patterns have changed to lavish and unessential patterns including embellishment of hotels, malls, etc. Increased industrial activity with respect to the use of water has increased the pressure on water resources. ...
The excessive industrial waste has significantly hampered the natural cleansing process, leaving previously fresh water, polluted and not useful for the purposes it was meant for. Human waste contributes significantly to the problem also. Every day, approximately 2 million tons of human waste are disposed in water courses (UN Water). The dilemma of developing countries is alarmingly bad, approximately 70 percent of all industrial waste is dumped into waters, leading to the pollution of usable water supply. Dangers of water pollution: All water pollutants are dangerous to humans as well as lesser species. Some of the key ingredients of the most prevalent pollutants, including industrial waste, include sodium, which is implicated in cardiovascular diseases; nitrates are guilty of causing blood disorders, whereas mercury and lead can cause nervous disorders. DDT, which is found in some forms of industrial waste, is toxic and can not only impact living humans but can also affect chromosomes. Another dangerous toxic ingredient found in industrial wastes, PCBs, is known to cause liver and nerve damage, skin eruptions, vomiting, fever, diarrhea and significant fetal abnormalities (Geol). The impact of pollution from sewage and human wastes is also lethal. Dysentery, salmonellosis and hepatitis are some of the diseases transmitted by sewage in drinking and bathing water. This problem is extremely frequent in developing and less developing countries where there is no clear mechanism to separate fresh and drinkable water from polluted water (Tripathi and Pandey). Causes of water pollution: The sources of water pollution can be divided into point sources and nonpoint sources. Point sources refer to factories, wastewater treatment facilities, septic systems, and other

The paper gives a definition of plastic and discusses the properties or characteristics of plastic that makes it so popular. Next, it discusses the benefits or the pros of using plastic and the consumption in the US. The next section of the paper takes a look at the cons of using plastic – the dangers posed by the use of plastic to the environment, to human health and to other animals. This research paper will attempt to show how the use of plastic will have detrimental effects on the environment and on our health.
Broad Straits of Mackinac join Lake Huron to Lake Michigan, and its waters are indivisible. Its lakeshore lengthens 3, 827 miles and is typified by low, sandy beaches and the stony shores of Georgina Bay (Mahler, Metre & Callender, 2006). Lake Huron gauges 206 miles crosswise and 183 miles north to south, with a mean depth of 195 feet to 750 feet maximum.
Lake Huron is an important source of fresh water to all the residents of the cities around it. It is also a home to a number of wildlife species (Shear, 2006). However, the lake has been adversely polluted over the years mainly based on the belief that water can dissolve anything.
The pollution can be biological, such as an unwanted bacteria and parasites. It may be a chemical which is known to cause cancer which has been discharged from an industrial waste site. Water can become polluted from agricultural runoff when toxic herbicides and pesticides mix with groundcover water and enters rivers and lakes.
The condition is so severe that it leads to outbreak of diseases mostly being contagious and lethal. The following paper seeks to look into the underlying causes and effects of water pollution.

The author states that water pollution is also a leading cause of healthcare concerns for humans and animals. Globally, approximately 500 million people do not have access to safe drinking water. Water pollution is caused when pollutants are indirectly or directly discharged into water bodies.
Even though this fact is recognized by humans, they disregard it by polluting lakes, rivers, oceans and seas. Water pollution causes many problems which includes diseases and killing of fish. Polluted water is also detrimental to human beings and animal life. The thesis will contend that water pollution comprises thermal pollution, industrial effluent and flooding.
Food supplies and provision of adequate food are problems that currently affect the human population because of lack of access clean and fresh water. It means different countries are unable to suggest preventive measures to safeguard humanity from succumbing to the dangers posed by both water shortage and its eventual pollution.
