Dear Editor,
I'm writing to tell you opinion about water saving.
Water is important. We, as well as animal, cannot live
without water and neither agriculture or industry can go
without it. Yet it seemed water is becoming less and less.
Many countries in the world find we don't have enough water.
To deal with a problem, I think, we should first go all 
out to plant trees though trees will help save water. Next, no
drinking water should be left running. Third, we could find
ways to reuse the water using in washing, especially bath 
water for which is quite a lot, and that will save much water.
Sincerely,
