Water
Water is very important in our daily lives. We need water to drink, take a shower or bath, water plants and so on. So, without water, life can't go on.
Most part of the Earth is covered by oceans, but ocean water is not drinkable. Groundwater may be drinkable, but it is not easy to find groundwater that is clean and safe to drink because people are polluting it We should try our best to save water. For example, we can take a shower instead of a bath. Turn off the tap when we brush our teeth.
