It is the contamination of water sources by substances which make the water unsuitable for different human activities. These activities can be drinking, cooking, cleaning and swimming. Harmful substances that pollute water sources include chemicals, trash, bacteria and parasites. The greatest factor that contributes to water pollution is that all forms of pollution eventually make their way to water. Both air and land pollution, settle onto lakes, rivers and finally end up in the ocean (Water pollution, 2013).

It consists of the contamination of the outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. The main sources that produce this type of pollution are motor vehicles, industrial facilities, combustion devices, household combustion devices and other natural disasters.

It refers to the destruction of the earth’s surface as a result of human actions or activities. Nearly every human economical activity from mining to agriculture or building has consequences towards the environment that may be intentional or unintentional. There are three human actions that are major contributors to land pollution, Legacy Pollution, Illegal Dumping and Littering. Legacy pollution consists of contaminated land from prior use of chemicals that have remained. Illegal dumping refers to the dumping of waste in non approved dumpsters. Littering is the action of leaving solid waste out in the open (Athens Clarke County, 2021).
