Why We Need Water!!!
Water is probably the most important resource on Earth. We need water to grow and stay alive. In fact, we could only live for a few days without drinking water. We also need water to grow plants and care for animals, cook our food, bathe and brush our teeth, flush the toilet, and wash our clothes.
Most of the Earth’s surface is covered in water. You might think that there is plenty of water for everyone to use. But did you know that most of the water on earth is ocean water? Ocean water is very salty. You can’t drink it or use it for growing plants, cooking food, bathing, or washing clothes. The water we use for these things is called freshwater.
