Water is very important!

Our planet has many oceans, many rivers, many water springs and without water nothing works. Even the electricity we use to turn on our computers is made with the help of water. When we eat, wash, clean the house we use water. You probably know that our bodies are made of water 90%, and even our blood is made of blood cells and Plasma, which comprises 55% of blood fluid, is mostly water (90% by volume)!
Keep the waters clean because you do it for your own good.
