WATER POLLUTION
AND CONSEQUENCES
ВА

2.

• Water pollution
occurs mainly when
people overload the
aquatic environment,
streams, lakes,
underground waters,
bays and seas, waste
or substances harmful
to living beings.

3.

• Plants and animals
need relatively
pure water, and
they will not survive
if there are toxic
chemicals or
harmful
microorganisms in
the water. Water
pollution kills a large
number of fish, birds
and other animals.

4.

• People who drink
polluted water can
get sick (cancer,
infectious diseases,
health problems in
future children).

*Have you asked yourself
the question, do the
wastes fall into the
ocean?
It turns out 75 g dry
weight in solid form per
person per day fall into
the ocean, and in the
world live more than 6
billion people.

Подведя итог, я хочу сказать, что
питьевой воды на планете
становится всё меньше и меньше и
её качество понижается. Я
призываю всех экономить и не
загрязнять воду.
