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 ef ects does this have on animal life and human society?

It is an undeniable fact that

water

plays an important role in human life. Nowadays, one of the major concerns of human beings is

water

pollution

, which can threaten both humans and the environment. In

this

essay, I will explore some of the issues and negative effects associated with

this

type of

pollution

caused by car's emissions and dumping wastes. One of the main causes of the problem is the emission which has been produced by vehicles.

In other words

, these emissions including damaging chemical particles,

such

as carbon and sulphur dioxide, can contaminate rainwater, runoff and

water

supplies.

For instance

, It has been confirmed by many scientists that the rate of

water

contamination in urban areas is often far more than in rural areas as many people in these cities tend to use their private cars, and

this

can ultimately release a huge amount of emissions into the air.

In addition

,

pollution

in the air can produce diverse types of diseases,

such

as respiratory diseases and eye irritation. It has been shown in the newspaper that 75% population of the urban areas has been seen in the hospitals due to these sicknesses. Another obvious cause of

water

pollution

is dumping wastes in the ocean.

This

is to say, sewage and trashes being released into the ocean can lead to marine

pollution

. Many poor countries,

for example

, dump household garbage into the seas as there are not enough landfills, and

this

can eventually pollute the ocean. Dumping these pollutants can become trouble for

water

species,

such

as fish, dolphins, and sharks.

This

can be the reason for the extinction of the sea species.

Also

, we have lost many types of

water

animals due to human activities. In conclusion, while human activities are the main cause of

water

pollution

and produce a number of obstacles for both humans and the sea environment. These problems can not be easily addressed. If the governments prohibited sea dumping and imposed stricter laws on the usages of private cars,

this

problem would be perfectly solved.
