Water kills thousands of people and destroys a lot of agricultural crops every year, But water also gives life to all living things in the world.
Without water life is undrinkable. We must have water to grow our food, feed the birds and animals in our homes, grow forests and produce electricity. We use waterways to carry our goods of trade. Even the human body Which is seventy parts out of one hundred, water itself cannot exist for long without water.
Ever since the earth began, large quantities of water have been used by living things. Yet for every drop of water that is taken from one place, another drop is put back somewhere else. Nature has a very clever way of carrying water from cloud to land and sea and back to cloud. No water has ever been lost.
But nature does not put water and when we need it. While some men are drowning, others in another part of the world are dying of thirst. Thus, people all over the world are trying to bring water to place where it is scarce to control its flow in times of floods and to make grcater use of it.
