  Without air, water and sunlight there would be no living things. Because they are so important, ecosystems 1 try to be very careful with these valuable resourses. Human beings often throw away things they have used only once. In good ecosystems, resources are used many times. The waste of plants and animals will become food for another. In fact, nature is much better at recycling than we humans are. Maybe we should learn from nature and become better recyclers—if we throw away too much, we may be throwing away our future.

We all care about nature and the environment, but we may not always do everything we could or should. Scientists who know a lot about the environment say that we should " Reduce, Reuse, Recycle and Respond". Let's see what that means.
