Pollution of rivers, lakes and seas is a major concern for people who seek to protect the environment. What are the possible causes of water pollution? And what effects does this have on animal life and human society?

Recently, more and more concerns about

water

pollution

have been heated, environmental departments are worried that the

pollution

of rivers, lakes and seas can result in problems for both animal life and human society. As far as I am concerned,

water

sources and

food

resources can be affected by the serious

pollution

caused by

factories

and tourism.

Firstly

,

factories

stand a high percentage of damaging the

water

. As the fee of treating

factories

wastes, chemical wastes and heavy metals in general, is usually high, some

factories

may leave those substances in the

water

as a way to due with it.

For example

, Japan has injected lots of radioactive resources into the sea which results in huge damage.

Secondly

, tourism will aggregate the

pollution

,

for example

, visitors may leave plastic bags or rubbishes on the beach, and those items may cause disaster once they flow into the ocean.

As a result

, both

animals

and humans are affected by environmental problems. As the

water

sources are polluted by the toxic compound,

animals

who drink the

water

may get sick. Eventually, some

animals

may lose prey and the

food

chain can be affected negatively.

On the other hand

,

water

which has been polluted can resist agriculture.

For example

,

food

can be poisoned by watering the polluted solutions, it can be dangerous for humans to mark the poisoned crop as

food

. In conclusion,

water

pollution

can be easily created by throwing wastes into rivers, lakes or seas whereas the damage to

water

can result in

food

shortages for both

animals

and humans.
