When do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?

The forest is a whole world of its own. It is full of many different living things. But even though they are all different, they have one thing in common: they all need each other in order to live on. The trees feed the forest

＂people＂ by making food in their leaves; by using sunlight to join water and minerals(礦物) from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.

Human beings are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and shop assistants to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Think how lonely and unhappy you would be if you lived all alone.

Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else. You know, being a volunteer is so great!
