【題目】

Our Earth is a blue planet. About 71 percent of the planet is water, but people can only use a small amount of it. Only about 3 percent of the world's water is fresh water. It's in lakes, rivers and underground. According to the UN, wastewater problems make water shortages (短缺) even more serious. Our homes, cities and factories make wastewater every day. It pollutes rivers and lakes.

People from different countries have their own tips for saving water.

In Australia most people have a grass lawn (草坪) around their home. They wash their cars on the lawn. The water will go to the grass!
