Pollution is the addition to the ecosystem of someting
which has a detrimental effect on it. One of the most important causes of
pollution is the high rate of energy usage by modern, growing populations.
Different kinds of pollution are found. In this section we will discuss:
Air Pollution.
Water Pollution.
Land Pollution.

Air Pollution
Air pollution is the accumulation in the atmosphere of
substances that, in sufficient concentrations, endanger human health or produce
other measured effects on living matter and other materials. Among the major
sources of pollution are power and heat generation, the burning of solid wastes,
industrial processes, and, especially, transportation. The six major types of
pollutants are carbon monoxide, hydrocarbons, nitrogen oxides, particulates,
sulfur dioxide, and photochemical oxidants.
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
nondegradable, bioaccumulative, 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.
