2. The purpose of the presentation is..
• We want people not to throw papers and plastics
because the rubbish contaminates the water a lot and
the animals die.
• We want boats not to throw oil to the water, because it
kills plants and wildlife.
• We want people not to waste water.
• We don’t want people to use pesticides in the water
because they kill fish and other animals.
• We want you, when you see a person throwing papers
and plastics to the water to tell them not to throw rubbish
anymore because they are contaminating the world.
• And we also want you to explain this presentation to
other persons and to become aware of this.

3. • The water cycle works
like this: sunlight causes
water to evaporate or dry
up into a gas called water
vapour. It rises into the
atmosphere and collects
in clouds, the vapor
condenses back into the
water and rains down to
earth to begin the cycle
again.

4. Factories pollute water,
but they are not the
biggest source of
water pollution.
Farmers use chemicals
that get into the soil
and pollute ground
water.

5. When the rain mixes with gases and falls, it
is acid rains and it is harmful to plants,
animals and even buildings. Some
pesticides also end up in the air and may
travel thousands of miles before settling in
stream, lakes, rivers, or the ocean.

6. • The boats strip oil, as
a consequence the
fish and the animals
die. They also die
because the people
contaminate the
water.

7. • Water pollution is a problem in many
countries. In the deserts the ground water
can lead to serious diseases.
• If the water we drink today is
contaminated we can die.
• The water we use today has been around
since the time of the dinosaurs.

8. • Dripping faucets
waste more water
than you think as
much as 20 gallons a
day !!!
So it is important to
care about the water
because it is good for
the life and wildlife.

10. In years around the 90’s
The water was not polluted.
Now the water is so
contaminated.
90… 2010

11. The good news is that the Earth has its own way of
cleaning up dirty water. It is the wetland way.
Wetlands are places that have shallow water or are spongy
at least some of the time. Marshes, swamps, tidal flats,
prairie photoles, and bogs are types of wetlands.

12. The conclusion is that we are responsable
for the contamination of water.
