Pollution is the introduction of a contaminant into the environment. It is created mostly by human actions, but can also be a result of natural disasters. Pollution has a detrimental effect on any living organism in an environment, making it virtually impossible to sustain life. Pollution harms the Earth’s environment and its inhabitants in many ways. The three main types of pollution are air pollution, land pollution and water pollution.
Air pollution is the accumulation of hazardous substances into the atmosphere that danger human life and other living matter. There are many natural sources of air pollution such as eruption of volcanoes, biological decay and lightning-caused forest fire. Naturally, the Earth already has its own air pollution loading. However, industrialization or just everyday routines has become added burden to the existing air pollution loading. The sources of air pollution can be categorized as industrial and development activities, motor vehicles, power generation, everyday routine and open burning.
Land pollution is pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities. Deforestation is one of the major causes of loosening of soil that causes soil erosion. The soil that is left naked on harvesting crops from agricultural lands is vulnerable to being eroded by wind and water. When contaminated soil is washed away in the water reservoirs, it leads to water pollution, which is lethal to the aquatic flora and fauna. The soil contaminants are driven by the wind, causing air pollution, which is detrimental to health.
Water pollution is the introduction of chemical, biological and physical matter into large bodies of water that degrade the quality of life that lives in it and consumes it. Water pollution occurs when a body of water is adversely affected due to the addition of large amounts of materials to the water. The sources of water pollution are categorized as being a...
