Although our earth is made of 20% land and 80% water, 97% of the water is salt water and only 3% of the water is fresh water. However, 3% of water contains 2% frozen water, which means there are only 1% of the water we can use. Water crisis is becoming a more serious now. 36% of the world’s population lacks access to improved sanitation. 780 million people live without access to save drinking water. Mortality rates remain hight without fresh, potable drinking water. Each year 3.6 million people die from water related disease. It’s time to save water now. What can we do? In fact, we can do more things to protect our planet.
