| ST AIDEN'S - SOUTH AFRICA WORLD ENVIRONMENT DAY What on Earth do We Know About Water? |
| What on Earth Do You Know About Water? Approximately 80 percent of Earth's surface is covered with water. Only one percent of this water is fresh we can use. 97 percent is saltwater. Two percent is water frozen in glaciers Earth's fresh water supply is limited and threatened by pollution. Today, have approximately the same amount of water as when the Earth was formed; Earth will not get any more water. Water moves in a never-ending cycle; nature recycles it over and over again. The water you drink may have been a drink for a dinosaur. You use an average of 168 gallons of water a day. In the United States, we use approximately 25 trillion gallons of fresh water each year. We are using our fresh water faster then we are recharging our groundwater. In the United States, more than 50 percent of our wetlands that recharge and purify ground water have been destroyed.
