Plant a tree and get air for free.
Feel free to plant a tree.
A tree that stay,
keep flood away.
Take care of the trees,
they will take care of you.

3. Pollution
• Pollution is the introduction of contaminants into a natural
environment that causes instability, disorder, harm or
discomfort to the ecosystem i.e. physical systems or living
organisms. 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.
• The Blacksmith Institute issues an annual list of the world's
worst polluted places. In the 2007 issues the ten top
nominees are located in Azerbaijan, China, India, Peru,
Russia, Ukraine and Zambia.

4. sources
• Pollution comes from both natural and man
made sources.
• Though globally man made pollutants from
combustion, construction, mining, agriculture
and warfare are increasingly significant in the
air pollution equation.

13. TYPES OF POLLUTION
• 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.

14. TYPES OF POLLUTION
• THERMAL POLLUTION
Thermal pollution is the discharge of waste heat
via energy dissipation into cooling water and
subsequently into nearby waterways.
• 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.

15. TYPES OF POLLUTION
• Solid Waste
• In the United States in 1988 municipal wastes
alone--that is, the solid wastes sent by
households, business, and municipalities to local
landfills and other waste-disposal facilities--
equaled 163 million metric tons (1980 million
U.S. tons), or 18 k (40lb) per person, according to
figures released by the Environmental Protection
Agency. Additional solid wastes accumulate from
mining, industrial production, and agriculture.

16. TYPES OF POLLUTION
• PESTICIDE POLLUTION
Pesticides are organic and inorganic chemicals originally
invented and first used effectively to better the human
environment by controlling undesirable life forms such as
bacteria, pests, and foraging insects. Their effectiveness,
however, has caused considerable pollution.
• RADIATION POLLUTION
Radiation pollution is any form of ionizing or nonionizing
radiation that results from human activities. The most well-
known radiation results from the detonation of nuclear
devices and the controlled release of energy by nuclear-
power generating plants (see nuclear energy).

17. TYPES OF POLLUTION
• NOISE POLLUTION
Noise pollution has a relatively recent origin. It
is a composite of sounds generated by human
activities ranging from blasting stereo systems
to the roar of supersonic transport jets.
Although the frequency (pitch) of noise may
be of major importance, most noise sources
are measured in terms of intensity, or strength
of the sound field. The standard

18. TYPES OF 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.
• Degradation of air quality and natural atmospheric
conditions constitute air pollution.
• It is defined as the presence of one or more
contaminants such as dust gas mist odor smoke smog
etc. Causes harm to human plants animals or property.
