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?

Water

contamination is a serious form of

pollution

that can lead to adverse effects

such

as drought, aqua erosion and contamination of marine ecology.

This

essay will identify the possible

cause

and effects of

water

contamination.

Firstly

, the main

cause

of

water

pollution

is the direct disposal of industrial activities. Numerous industries have been discharging toxic chemical compounds

such

as metallic sulfides or cyanides. When being introduced into lakes, rivers, and seas without filtration, these toxic wastes poison

animals

and plants,

consequently

destroy the ecosystem. Even when the industrial

waste

is buried in the ground, it can still permeate the soil to pollute the underground

water

,

thus

begin the process again.

Secondly

, another

cause

is due to overcapacity of landfills. The poor

waste

management inland leads the

waste

to be thrown in seas. Without the recycling process, the plants of the sea could be damaged,

hence

seas

animals

would consume the

waste

accidentally.

For instance

, a year ago a shark was found dead on the beach of Bali. People found out that there were many plastics inside the shark.

Last

but not least, the other

cause

is the

oil

spill. A disaster happens if crude

oil

is leaked from a petroleum tanker, which is

also

a reason for sea

pollution

. Most marine

animals

cannot digest

oil

, or cleanse the spilling

oil

on their feathers.

Therefore

, they will die soon unless there are human interventions. The spill

also

adversely affect seawater, which damages the tourist industry of coastal regions. To summarize,

water

pollution

is mostly the result of

oil

spills and industrial or human

waste

disposal. It severely affects the environment and

subsequently

the life of

animals

and humans.
