Adequate sanitation helps to keep sewage and other contaminants from entering the water supply.
According to National Oceanic and Atmospheric Administration (NOAA), 80% of pollution in marine environment comes from the land through sources like runoff.
According to the EPA, low levels of dissolved oxygen in the water are also considered a pollutant.
Dissolved is caused by the decomposition of organic materials, such as sewage introduced into the water. The artificial warming of water is called thermal pollution.
"In nearly all cases, 90% of this water is returned to its source, where it can raise the water temperature in an area immediately surrounding the water discharge pipe.
Depending on water flow, the water temperature quickly returns to ambient temperatures that do not harm fish." Donn Dears, former president of TSAugust, a not for profit corporation organization focused on energy issues, told Live Science.
Water pollution happens when chemicals or dangerous foreign substances are introduced to water, including chemicals, sewage, pesticides and fertilizers from agricultural runoff, or metals like lead or mercury.
According to the Environmental Protection Agency (EPA), 44% of assessed stream miles, 64% of lakes and 30% of bay and estuarine areas are not clean enough for fishing and swimming.
According to the EPA, the greenhouse effect is when gases absorb the infrared radiation that is released from the Earth, preventing the heat from escaping.
This is a natural process that keeps our atmosphere warm.
