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?

Nowadays, there are many

water

sources that are polluted.

Additionally

, many people are concerned about these problems and their effects on the environment. There are two main factors that cause

water

pollution, which are industrial

waste

and fuel spills. The consequences of these problems are dirty

water

sources for animals and infected seafood for humans. These are causes and effects, which we will discuss

further

in the essay. Many developed countries have a demand for producing goods.

Therefore

, a lot of factories have been built, and

waste

from factories has polluted lakes, rivers, and seas. To be specific, most industrial

waste

contains chemicals that negatively affect

water

. As evidence, many studies have found that billions of tons of industrial

waste

are dumped into the

water

each year.

Although

we can filter the polluted

water

into fresh

water

, the amount of contaminated

water

is too high to filter.

Besides

, spilling oil in the ocean

also

contributes to an increase in

water

pollution. In fact, millions of litres of oil are spilt into the ocean each year

due to

various ship accidents.

As a result

of

water

pollution, many negative effects have caused major and serious problems for the ecosystem and individuals. Because of the high levels of chemicals in contaminated lakes and rivers, many species of fish have become extinct or poisoned.

On the other hand

, a lot of ground animals can not survive

due to

a lack of food and clean

water

. As a matter of fact, many species have to immigrate because of the contaminated sources of

water

in their living habitats.

Furthermore

, polluted oceans make these sea creatures unsafe to eat, but many people around the world consume seafood every day. To be specific, most sea creatures living in areas with high levels of chemicals contain a high amount of disease and illness for humans.

For instance

, many records show that consumers of dirty seafood have a high chance of getting heart disease and nausea. In conclusion, many are worried about polluted

water

and its effect on the ecosystem. Industrial

waste

and oil spills are the two main causes of contaminating

water

, these phenomena lead to a shortage of clean

water

for animals and infected sea creatures humans to consume.
