Air pollution
Air pollution is a very
serious problem. In big
cities more and more
factories, cars and trucks
add their bad breath to
the air.
The greenhouse effect is a warming when the earth's atmosphere traps
the sun's heat. Carbon dioxide, methane, nitrous oxide and other
greenhouse gases absorb the radiation rising from the earth and holds this
heat in the atmosphere instead of reflecting it back into space.
It’s important!
It's very important for us to
“clean up our act”. Everyone can
help keep our air clean and safe.
You can plant a trees and ride your
bikes.
It protects the Earth from the violet rays sent down the sun. If the
ozone layer is depleted by human action the effects on the planet
could be catastrophic. Because the ozone layer protects both
plant and animal life on the planet.
The ozone hole for the first time
was discovered in 1985, at the
southern hemisphere, over
Antarctica.
Why it is dangerous for us?
Around the Earth there is a special
type of oxygen called “ozone”.
Ozone is important because it
stops ultraviolet radiation from
the sun. Many aerosol sprays and
factories destroy ozone and they
have made a very big hole in the
ozone layer. This is very dangerous
because it can cause cancer.
The world has over 9
million square km of
forests. But they are
disappearing fast.
Forests are very important for us. We need them! The
trees and other plants in the forest help to make the
air that we breath. They also help to control the
weather. They give us wood, rubber, fruits and many
of our medicines.
