Approximately 75 percent of the Earth's surface is covered in water. So why is water considered such a precious resource?

• The greenhouse effect is causing most of the world's freshwater to be trapped in the atmosphere
• Only a small fraction of the Earth's water is freshwater available for drinking and irrigation
• Each year, more freshwater is being trapped in icecaps located at the North and South Poles
• Global warming caused by greenhouse gas emissions will likely cause Earth's oceans to evaporate
