Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence. Thermal pollution, unlike chemical pollution, results in a change in the physical properties of water. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. [46]
Today, industrial pollution is caused by discharges and emissions from manufacturing plants in certain industries, which continues to pollute surface waters nationwide. [39] Many manufacturing processes generate wastewater, contributing to the water pollution found in rivers, lakes, and oceans. [40]
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [153]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come ...
Urbanization destroyed the natural habitat and industrial development led to water pollution and exploitation of natural resources. [22] In 1971, when the United Arab Emirates was founded, the country´s population was approximately 300 000 people. Today, the country has over 9 000 000 citizens while 89,5% live in urban areas.

A further spike in levels of human-caused lead pollution was observed about 2,150 years ago. This period saw the expansion of the Roman Empire across the Aegean region , which hosted some of the ...

As a result, the overall water level decreases. This may cause water mining, land/soil subsidence, and, along the coast, saltwater intrusion. Irrigated land area worldwide occupies about 16% of the total agricultural area, and the crop yield of irrigated land is roughly 40% of the total yield. [5]
The consumption of polluted water leads to many deaths. In the year 2015, 1.8 million people world wide died because of water pollution and over 1 billion people became ill. [8] Low-income and third-world communities are especially endangered, because they often live close to industries with high emission. [8]
