3. Some Basic Info about WATER:
Water is essential for survival on Earth. It makes up almost
2/3 of our body weight and covers a little over 2/3 of the Earths
surface. Almost all of the water is in salty seas, and we can’t
use it. Only 2,5 % of it is fresh and ¾ of it is frozen.
o
So only 1% of the water in Earth is available for
humans to use.
o
o
We describe water as a colorless, odorless, tasteless liquid.
Water also comes in the form of ice in the polar ice cups, and
water vapor that rises in to the air from the surface of our
planet.

4. Where the Water comes from??
All the water that flows in steams has to come from
somewhere. All of this water comes from the sky, mostly in
the form of rain and snow.

5. Where the Water comes from??
When it rains, some water flows over the ground,
eventually joining a stream. Much more of the rain water
seeps down in to the soil, moving slowly underground until
it finds a stream or lake to join.

6. Water is a critical issue for the survival of all living
organisms. Some can use salt water but many
organisms including the great majority of plants
and mammals must have access to fresh water
to live…

7. So people also are depended of the Water BUT
…….

8. THEY POLLUTE IT…………

9. Sources of WATER pollution

Agriculture including
fertilizers, pesticides etc.
How the water is polluted??
Agriculture
including toxic and
nontoxic chemicals
Fertilizers
Pesticides
Industry
Chemicals
Oil Spills
Liquid waste
Contamination
 Industry

Municipal uses, including
human waste
Human waste

10. #1  Agriculture
Agricultural pollution refers to biotic
and abiotic by products of farming
practices that result in
contamination or degradation of
the environment and surrounding
ecosystems, and cause injury to
humans and nature.

11. #2  Industry

12. Also….
Oil spills: ….cause major problems, and can be extremely
harmful to local marine wildlife such as fish, birds and sea otters
and other aquatic life. Because oil does not dissolve, it stays on
the water surface and suffocates fish.

13. #3  Human Use
Everyday, we cook, do laundry, flush the toilet, wash our cars,
shower and do many things that use water. Think about how we
use water in schools, hospitals and public places. Where do you
think all the water, liquid waste, toilet and urine ends up?
In many developed communities, this waste water is treated,
cleaned and dumped into the sea. Even though they are treated,
they are never the same as fresh water.
In some not-so-developed countries, the sewage is not treated, but
quickly dumped into the sea or water bodies. This is VERY
dangerous because they contaminate the environment and water
bodies and bring many deadly diseases to us.

14. Effects of Water Pollution

15. Disruption of food chain- Ecosystems
Pollution disrupts the natural food
chain as well. Pollutants such as
lead and cadmium are eaten by
tiny animals. Later, these animals
are consumed by fish and
shellfish, and the food chain
continues to be disrupted at all
higher levels. Ecosystems (the
interaction of living things in a
place, depending on each other
for life) can be severely changed
or destroyed by water pollution.

16. Death of aquatic animals …
The main problem caused by water
pollution is that it kills life that depends on
these water bodies. Dead fish, crabs, birds
and sea gulls, dolphins, and many other
animals often wind up on beaches, killed
by pollutants in their habitat (living
environment).

17. Diseases ….
Eventually, humans are affected by this
process as well. People can get diseases
such as hepatitis by eating seafood that has
been poisoned. In many poor nations, there
is always outbreak of cholera and diseases
as a result of poor drinking water treatment
from

18. Many areas are now being affected by careless human
pollution, and this pollution is coming back to hurt humans in
many ways.
WHAT CAN WE DO??

19. WE CAN HELP…
1. Never throw rubbish away anyhow. Always look for the correct
waste bin. If there is none around, please take it home and put it in
your trash can. This includes places like the beach, riverside and
water bodies.

20. WE CAN HELP…
2. Use water wisely. Do not keep the tap running when not in use.
Also, you can reduce the amount of water you use in washing and
bathing. If we all do this, we can significantly prevent water
shortages and reduces the amount of dirty water that needs
treatment.

21. WE CAN HELP…
3. Do not throw chemicals, oils, paints and medicines down the sink
drain, or the toilet. Buy more environmentally safe cleaning liquids
for the use at home and other public places. They are less
dangerous to the environment.

22. WE CAN HELP…
4. If you use chemicals and pesticides for your gardens and farms,
be mindful not to overuse pesticides and fertilizers. This will reduce
runoffs of the material into nearby water sources. Start looking at
options of composting and using organic manure instead.

23. WE CAN HELP…
5. If you live close to a water body, try to plants lots of trees and
flowers around your home, so that when it rains, chemicals from
your home does not easily drain into the water.
