Did you know the following facts about water?
There is about the same amount of water on Earth now as there was millions of years ago.
Nearly 97 percent of all the world’s water is salty or otherwise undrinkable. Another 2 percent is ice. Then there only leaves 1 percent for all our needs.
Water regulates (调节) the Earth’s temperature. It also regulates the temperature of the human body!
More water is used in the bathroom than any other place in the home.
A dripping faucet (龙头) can waste up to 7,570 L of water a year.
Amazing? Then why not help to save water? You should know that whether at home or at school, you can do things like this to save water:
◆ Turn off the water in your bathroom while you brush your teeth.
◆ Take shorter showers.
◆ Don’t let the water run constantly（不间断地）while you’re washing dishes.
◆ Fill a bottle with tap water and put it in the fridge, rather than running the water every time you want a cold drink!
◆ Repair dripping faucets.
