to help down drive ride

Natural resources are things that we use that come from Earth. Our natural resources are limited (有限的). This means that they will not last forever. Some are renewable, like when you plant a new tree when you cut one .Others are not renewable, like when you dig coal (煤) out of the ground. Once it is used, it is gone.
People realize the fact that Earth's natural resources are limited, and can do things conserve (節(jié)約) those resources. When you try to conserve a natural resource, you try to use less of it so it does not get used up so fast. One way that people conserve fuel, like gasoline, is by a bicycle or walking when the distance is short instead of everywhere.
Water is a very important natural resource because we all need it to stay alive. We can conserve water by making sure that our pipes and taps do not leak (漏). We can also make surprising choices to conserve water, like only using the dishwasher or washing machine when they are full. Everyone can make contributions protecting natural resources.
