Water

The video is about a poor girl who only can access to dirty water or lagoon water. Also appears ah boy of a higher society class that give to girl a pure water bottle that was of him.  I think this videos shows the disfortunaly situation that many people is suffering and that we can help them a little so they can be better.

Water Uses	Examples
Industrial uses	Hydroelectric power stations, heavy water uses in nuclear reactors (it is chemically modification).
Cotidian uses	Drink, uses to take a bath, etc.
