explanation[1]="About 30% of the Earth\’s surface is covered in land (the seven continents) but 70% is covered with water. Most of this water is salt water, found in oceans. The rest is fresh water (water with no salt), which is found in icecaps, glaciers, lakes, rivers, streams, in animals and plants and under the ground. Only less than 1% of all water on Earth is usable to humans."
explanation[2]="Water cycles around and around: The water you drink today might be the same water that dinosaurs drank millions of years ago! It changes form from liquid to gas through evaporation, condenses into clouds and precipitates down as rain, snow and hail. Some of it infiltrates through soil and becomes groundwater. Water absorbed by plants might be released as a gas back into the atmosphere through a process called transpiration."
explanation[3]="All living things need water to live. Our bodies are 70% water. It makes up 83% of our blood, 70% of our brain and 90% of our lungs! We should drink six to eight glasses of water each day and eat plenty of fruits and vegetables (which also contain water) to stay healthy."
explanation[4]="The average U.S. citizen uses 100 gallons of water per day! Most of this water is used for flushing the toilet and watering lawns and gardens. Other activities like drinking water, taking a shower and brushing your teeth use water too."
explanation[5]="A leaky toilet can waste about 200 gallons of water every day, so fixing it saves a lot of water! You can save 150 gallons of water by turning off the hose in between rinses while you help to wash your family car, and up to 30 gallons a day by taking five-minute showers. The average bathroom faucet uses 2 gallons of water per minute - shutting off the water while you brush your teeth every morning and evening can save up to 8 gallons a day! Conserving water is important all year long, and you can help. How will you be water wise today?"
