Water pollution
What is water ?
Water is a colorless, tasteless and odorless liquid. We use water to drink and wash ourselves. Also water is used in industry . What is more, water is used to produce electricity : it turns turbines in water power stations . This colorless, odorless and tasteless liquid is an inherent part of this world.
Spilled oil and its products...
...pollutes the water too. Oil spills in the sea when the ship expands or have a serious accident. When oil is in the water is makes air - impermeable skin, so water animals can not breath and die .
Humans...
...pollute the water too. Many humans drop various litters in the water, because it is an easier way to rid litter, than bring them to the bin .

Paulius Maciulevičius,
Dominykas Rimdeika,
Domantas Melys.

Some solutions to stop water pollution.
Solution No.1
Firstly the government should build more water cleaning machines, to clean water, because just 22 % of contaminated water from cities is totally cleaned.
Solution No.2
Secondly, the government should reduce oil transporting by seas and oceans. Then it will be lesser accidents of oil tankers .
Solution No.3
Finally, the government should build more bins near water reservoirs, especially in the parks near lakes or rivers. Then humans drop litter into bin instead of dropping them to water.
Thank you for your attention
In water live many aquatic animals : fish, turtles, mussels and many more . If the water is polluted all of the aquatic animals die, because they can not live in very polluted water.
