We must stop polluting our water. Even if we succeed in making more water available to us ,we must still do something about water pollution. We are polluting water at an alarming pace .Cars ,factories ,and air conditioners pollute the air and the water. We must change the way we think and the way we live . Let’s not drive if we can walk or ride a bike . Let’s try not to use air conditioners more than what is absolutely necessary. Let’s not buy products that cause pollution. Let’s make new rules and use new technology to make sure that factories are green and clean. Keep in mind that we –you and I—are the ones who must change. This brings me to my final point: we must stop using too much water in our daily life .

我们必须停止污染水。即使我们能够成功地制造出更多的可用水，我们还必须对水的污染采取行动。我们正在以惊人的速度污染着我们的水。汽车、工厂和空调污染着我们的空气和水。我们必须改变我们的思想和生活方式。如果能走路或者骑自行车，那我们就不要开车。在绝非必要的时候让我们不要使用空调。让我们不要购买能引起污染的产品。让我们制定新的法规和使用新的科学技术去确保我们的工厂是绿色和环保的。我们、你和我，我们中的每一个人都必须做出改变去遵守这一规则。这就是：让我们在我们的日常生活中节约每一滴水。
