Land, Air and Water Pollution

Air Pollution

Air pollution is the accumulation in the atmosphere of substances that endanger human health or produce other measured effects on living matter and other materials. Among the major sources of pollution is the burning of solid wastes, industrial processes, and, especially, transportation.

Water Pollution  

Water pollution is the introduction into fresh or ocean waters of chemical, physical, or biological material that degrades the quality of the water and affects the organisms living in it. This process ranges from simple addition of dissolved or suspended solids to discharge of the most insidious and persistent toxic pollutants (such as pesticides, heavy metals and chemical compounds).

 Land Pollution

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.
