Pollution may be defined as addition of undesirable material into the environment as a result of human activities. There are, also, other definitions. Some of them are; → Pollution is the contamination of soil, water, or air by discharging harmful substances. → Pollution is the introduction of contaminants into an environment, of whatever predetermined or agreed upon proportions. This occurs when only short-term economic gains are made at the cost of the long-term ecological benefits for humanity. → Pollution is the effect of undesirable changes in our surroundings that have harmful effects on plants, animals and human beings. “Harmful” mean an adverse effect on adverse effect on anthropogenic or natural non-living structures, or a reduction in the air‟s visibility Pollution can happen in different form. o These contaminants, in general, cause instability, disorder, harm or discomfort to the physical systems or living organisms therein. The agents which cause environmental pollution are called pollutants. → Pollutants may be defined as a physical, chemical or biological substance unintentionally released into the environment which is directly or indirectly harmful to humans and other living organisms. → Pollutants can be classified into

The importance of the environmental pollution lies in its great impact on human life and the surrounding environment. In addition to its disastrous results that extend for many years, it contributes to crystallize the life of man, animal, and plant. The research discusses the concept of environmental pollution, and all the undesirable changes that occur in the environment. It sheds light on the causes of pollution, especially radiation and chemical types result from cars, fumes, gases, smoke and industrial wastes, which included liquid, solid wastes and others. It emphasizes air pollution, its causes, sources, and effects on humans, animals, plants, and the weather. It has a major role in making a foremost change in temperatures degree. Conceivably, the waste is extremely dangerous, and the smoke, fumes, toxins and unpleasant odors of factories and cars cause a fuel combustion with all its preventive measures and procedures. There is no doubt that the expansion of transportation means will negatively affect the percentage of environmental pollution. The research debates the most important factors and causes of water pollution due to throwing liquid and solid wastes into rivers and lakes. The causes of soil and plant pollution can be linked to the use of large quantities of pesticides and chemical fertilizers, which affect the quality of agricultural crops and reduces their fertility. They contribute to the loss of their beneficial organic materials, which harmfully disturbs the life of both humans and animals.

Modern economic development sometimes disrupts nature’s delicate balance. The extent of environmental pollution caused by humans is already so great that some scientist question whether the Earth can continue to support life unless immediate corrective action is taken. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Much of the world’s air, water and land are now partially poisoned by chemical wastes. Some places have become inhabitable. These pollution exposes people all around the globe to new risks from disease. As a result of these developments, governments have passed laws to limit or reverse the threat of environmental pollution. The 19th century, industrial revolution placed greater pressures on the environment. Although industrial development through the control of nature and development of new products improved the standard of living of humans, this was at a great environmental cost.
