Water Pollution is
the contamination of
the natural
environment with
harmful substances
often as a
consequence of
human activities.

change in the state of water,
contaminated with harmful substances.
It is the second most important
environmental issue next to
air pollution.

differents types of
pollution as:

chemicals, sewage and fertilizers are

into waterways,
serious pollution

8. CAUSES
Domestic households, industrial and
agricultural practices produce
wastewater that can cause pollution of
many lakes and rivers.

9. Dumping of litter in the sea can cause
huge problems in marine animals and
may result in death.

10. Nuclear waste is
produced from
industrial, medical and
scientific processes
that use radioactive
material. Nuclear
waste can have
detrimental effects on
marine habitats

11. The effects of water
pollution are not only
devastating to people
but also to animals,
fish, and birds.
Polluted water is
unsuitable for
drinking, recreation,
agriculture, and
industry.
Effects of water
pollution

12. • poisoning drinking
water
• poisoning food animals
• unbalanced river and
lake ecosystems that
can’t support full
biological diversity
any more
• deforestation from
acid rain, and many
others.

13. prevent water pollution?
• Be careful about what
you throw down your
sink or toilet.
• Use environmentally
household products,
such as washing
powder, household
cleaning agents and
toiletries.
• Take great care not
to overuse pesticides
and fertilisers.
• Don't throw litter
into rivers, lakes or
oceans.

14. Planting more trees can also prevent water
pollution by reducing soil erosion and water
runoff i think that educating people about
water pollution is an important way of
preventing water pollution.

15. CONCLUSION
I think that we have to change our
habits because the water is a
natural resource very important
and if we follow the same way till
now, one day maybe our sons woke
up and they won´t have water to
drink.So,for future,save water.
