surface of our Mother Earth. The major causes of pollution are mostly linked to the growing number of population, industrial developments and technological advancements.
Pollution is defined as the contamination of chemical substances or agents into an environment that causes imbalance, disorder, harm or discomfort to the physical systems or living organisms. There are three basic types of pollution. These are air pollution, water pollution and land pollution.
Air pollution is the accumulation of substances in the atmosphere that endangers human health or produces other measured effects on living organisms.
Water pollution is contamination of chemical, physical, or biological substances that degrades the quality of the water and affects the organisms living in it.
Land pollution is the degradation of the Earth's land surface through misuse of the soil by poor agricultural practices, mineral exploitation, industrial waste dumping, and indiscriminate disposal of urban wastes. It includes visible waste and litter as well as pollution of the soil itself.
The problem in pollution has produced physical and biological effects that vary from mildly- irritating to lethal. The physical effects of pollution are those we could observe such as oil spills. This spoils the beauty of nature by killing our marine life and birds. This also makes beaches unusable. Another physical effect is soil erosion that causes landslides.
The most serious result of pollution is its harmful biological effects on human health and on the food chain of animals, birds and marine life. It can seriously disrupt the balance of nature. In extreme cases, it can cause the death of humans.
As humans, we need to protect and preserve the beauty of our Mother Earth. The destruction of our nature can result to the destruction of humanity. We all live on one Earth. We can suffer the effects when we do things that pollute our nature.
