Answer 1

water is the source of our life.
70% of our planet is water.
but most of the water cannot be used.
so we still have to save water.
when we are brushing our teeth ,we need to turn off the tap.
we shoule learn to reuse the water as well.for example ,we can use the water which has been used to wash the vegetables to water the plants.
