The environment has been polluted in many different ways. The three major ways are water, land, and air pollution.Water pollution is the contamination of lakes, caused by human activities. It can be harmful to organisms and plants which live in the water. Water pollution occurs when wastes are discharged from wastewater treatment plants. Other known causes are factory wastes or leaking underground tanks. These can be chemical substances that are toxic. The polluted water can cause cholera and typhoid fever. Water pollution has led to the deaths of more than 14,000 people daily.

Land pollution is the destruction of the earth’s land surfaces. It is often caused by human activities such as careless disposal of wastes, over-mining of minerals, and wrong use of land for planting. All these will affect our health in the long run. They will lead to all kinds of diseases such as cancer, heart disease, and breathing problems. Land pollution also brings about natural disasters such as flash floods and landslides.

Air pollution is also the result of human activity where chemicals and other dangerous materials are released into the air. This happens through the release of carbon monoxide gas from the exhaust pipes of motor vehicles. Other gasses such as sulfur oxides are released from the burning of coal and oil. High air pollution levels can cause damage to the environment. It also brings discomfort to humans and other living organisms. In the long term, air pollution can cause serious breathing problems, lung cancer, and heart disease.
