I understand that water is very important because water is in many places: in the clouds; in rivers, in snow and in the sea. It is also where we can not see, like the air itself, in our body, food and underground. Also, the water changes from place to place. Water is necessary for the life of humans, animals and plants. An important part of the wealth of a country; so we must learn not to waste it. We all know that water is essential to life and if we fail to take die within days.
70% of our body consists of water; found water in the blood, saliva, inside our cells, between each of our organs, our tissues and even bone. Besides drinking water, we humans use water in almost all our actions, ie we require it to prepare food, wash clothes or dishes, grooming, watering crops, animal husbandry, product manufacturing, energy production , etc.
