The number of cars on the world's roads surpassed one billion
last year, according to a study that has spurred debate on what
the rapidly-growing car population will mean for the world's
economy and environment.
HOW MANY CARS ARE THERE
IN THE WORLD?
Air pollution can result from both human and
natural actions. Natural events that pollute
the air include forest fires, volcanic
eruptions, wind erosion, pollen dispersal,
evaporation of organic compounds and
natural radioactivity. Pollution from natural
occurrences are not very often.
1. Burning of Fossil Fuels
Sulfur dioxide emitted from the combustion of fossil fuels
like coal, petroleum and other factory combustibles are
some of the major cause of air pollution. Pollution emitting
from vehicles including trucks, jeeps, cars, trains, airplanes,
ship cause an immense amount of pollution .
CAUSES OF AIR POLLUTION
2. AGRICULTURAL ACTIVITIES
Ammonia is a very common product from
agriculture related activities and is one of the
most hazardous gases in the atmosphere. Use
of insecticides, pesticides and fertilizers in
agricultural activities has grown quite a lot.
3. EXHAUST FROM FACTORIES AND INDUSTRIES
Manufacturing industries release large
amounts of carbon monoxide, hydrocarbons,
organic compounds, and chemicals into the
air thereby depleting the quality of air.
4. INDOOR AIR POLLUTION
Household cleaning products, painting supplies
emit toxic chemicals in the air and cause air
3. ACID RAIN
When it rains, the
combined with these
air pollutants, become
acidic and then falls
on the ground in the
form of acid rain. Acid
rain can cause great
damage to human,
animals and crops
4. EFFECT ON WILDLIFE
Just like humans, animals also
face some devastating affects
of air pollution.
Toxic chemicals present in the
air can force wildlife species to
move to new places and
change their habitats. The toxic
pollutants deposited over the
surface of the water can also
5. DEPLETION OF OZONE LAYER
Ozone exists in earth’s
stratosphere and is
responsible for protecting
humans from harmful
ultraviolet (UV) rays.
Earth’s ozone layer is
depleting due to the
in the atmosphere
THIS IS HOW OUR WORLD WILL LOOK LIKE IF WE CONTIN
POLLUTING THE EARTH LIKE WE DO NOW
