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?

The topic of contamination of

water

areas becoming increasingly actual nowadays.A lot of people all over the world paid attention to

this

concern .So let us

this

topic more deeply .

Firstly

,we can not deny the fact that humanity is the cause of

water

infection .Many factories drain waste into rivers .Probably ,they are doing it because top brass thinks that it is too expensive to recycle waste material properly.

Nevertheless

,contamination of

water

does not always happen out of human greed.Sometimes it occurs accidentally.

For instance

,a shipwreck and

as a result

fuel which was on the ship got in the

water

.

Secondly

,

water

pollution creates a lot of problems for human society as for

animals

.Thousands of

animals

died per year and millions suffer from

this

contamination .We can observe a lot of photos and articles on the internet about it.And they all about which effects it is have for the animal world.Pollution of rivers, lakes and seas mostly decrease the population of fish who lives there.But ,in nature everything is connected and if one of these

chanes

changes

will disappear

then

others too.

For example

,if the fish are smaller

then

the

animals

that feed on them start to starve and their populations decrease and so on.

Also

,it is affected humanity too.Without ,

animals

we do not have enough to eat. To draw the conclusion ,I can say that pollution of

water

areas is a major concern of 21 century .We should protect our environment because if we do not do it we and our children will leave in a world where everyone suffers.
