Answer 2

The first - most important way to consume water is to plant trees. As we knew, trees help slowing down the rain water's speed, which pervents floods in plateaus, mountains, etc. When dropping down, part of the water stays on the leaves, branches, when the remaining one come into the ground, creates humid in the current habitant and fills up the underground water "path" - the main source of people's water. The underground water runs into low land, appear to the surface, which makes up nearly 100% rivers and deltas in the world. Trees also contribute an important part in preventing droughts. And we should prevent human hands from trying to destroy too much trees for wood.

The second important way to consume water is an easy one: to use water in a economical way, such as turn off the faucets after using, take showers instead of baths, or use dish-washing machine instead of washing them by hand.
