Pollution is the introduction of contaminants into the natural environment that cause adverse changes. There are several main types of pollution: Land pollution occurs when land surfaces are destroyed through misuse of resources, depositing rubbish and garbage. Air pollution introduces chemicals, particulates, or biological materials into the atmosphere, endangering human health and ecosystems. Water pollution is the contamination of water bodies like lakes and rivers when pollutants are discharged without treatment, affecting plants and organisms living there.

2. WHAT IS POLLUTION?
*Pollution is the introduction of
contaminants into the natural environment
that cause adverse change.[1] Pollution can
take the form of chemical
substances or energy, such as noise, heat
or light. Pollutants, the components of
pollution, can be either foreign
substances/energies or naturally occurring
contaminants. Pollution is often classed
as point source or nonpoint source
pollution.

4. * Land pollution is the destruction of Earth's land
surfaces through misuse of land resources by
human activities. Polluted land has deposits of
liquid and solid waste such as rubbish, garbage,
paper, glass and plastic objects.

5. * Air pollution is the introduction into
the atmosphere of chemicals, particulates, or biological
materials that cause discomfort, disease, or death to
humans, damage other living organisms such as food
crops, or damage the natural environment or built
environment.
* The atmosphere is a complex dynamic natural gaseous
system that is essential to support life on
planet Earth. Stratospheric ozone depletion due to air
pollution has long been recognized as a threat to human
health as well as to the Earth's ecosystems.
* Indoor air pollution (see Airlog) and urban air quality are
listed as two of the World’s Worst Toxic Pollution Problems in
the 2008 Blacksmith Institute World's Worst Polluted Places
report.[1

* Water pollution is the contamination
of water bodies
(e.g. lakes, rivers, oceans, aquifers and groundwate
r). Water pollution occurs when pollutants are
directly or indirectly discharged into water bodies
without adequate treatment to remove harmful
compounds.
* Water pollution affects plants and organisms living
in these bodies of water. In almost all cases the
effect is damaging not only to
individual species and populations, but also to the
naturalbiological communities.
