Air and water pollution are caused by a variety of human activities and can harm human health and the environment. Air pollution includes smog from vehicle emissions and industrial activities, acid rain from sulfur dioxide and nitrogen oxide, the greenhouse effect from carbon dioxide trapping heat, and destruction of the ozone layer from CFC emissions. Water pollution occurs when waste is dumped into water sources, contaminating the water and affecting both wildlife and humans who use the water. Reducing pollution requires changes in individual lifestyles as well as industrial practices.
2. What is Air Pollution?
• Air supplies us with oxygen which is essential
for our bodies to live.
• There are several main types of pollution .
These include smog, acid rains, the green
house effect, “hole” in the ozone layer.
• One type of air pollution is the release of
particles into the air.
3. • Another type of pollution is the release of
noxious gases.
• Pollution also needs to be considered inside
our homes, offices, and schools.
5. • Smog is a type of large
scale outdoor pollution. It is caused by
chemical reactions between pollutants derived
from different sources.
• Cites are often centers of these types of
activities

7. Acid rains
• It’s caused when a pollutant combines with
droplets of water in air.
• The effects of acid rain on the environment can
be very serious.

9. Greenhouse effect
• It generally comes from the build up of carbon
dioxide is gas in the atmosphere. Carbon
dioxide is produced when fuels are burned.
• In this type of pollution sun rays go into the
atmosphere and they are trapped by
greenhouse gasses. So the temperature on the
earth raises.
10. Hole in the ozone layer
• It is another result of our activities affect the
stratosphere.
• Releases of CFC from heating, aerosol cans
refrigerator equipment removes some of the
ozone, causing “holes”.
11. Indoor air pollution
• It’s more dangerous than the outdoor pollution,
because we do everything in enclosed
environments where air may be restricted.
• There are many sources of indoor air pollution
:
Tobacco smoke, cooking and
heating appliances, and vapors from building
material.
12. Health effects
• Some individuals are much more sensitive to
pollutants than others.
• Air pollution can affect our health in many
ways with both short and long term effects.
13. Prevention
• Air pollution prevention efforts of companies
have generally focused on waste reduction,
reuse and recycling
• So to solve these problems and to get over
them we can change our lifestyles.
• If we do these simple things we could have a
better world.
14. Water Pollution
• Water pollution occurs when energy and other
materials are released into the water, contaminating
the quality of it for other users.

16. Different Causes of Water Pollution
• Marine Dumping
• Industrial Waste
• Sewage, mainly from households
• Nuclear waste
• Underground storage leaks
