A forest is a special place. In the forest, surrounded by tall trees, you are cut off from the would around you, and filled with the sights and sounds of nature. Many fairy tales and legends are set in forests, which have been thought to hold magic and mystery. Today we know that these are only stories, but the forest is still a place that holds many of the world's most valuable resources.
Forest has always been important to people. In the past, many people got food by hunting forest animals and gathering wild plants. With the advance of civilization, fewer people now live in forests, but forest are more valuable than ever. Forests have an important economic value because they provide us with resources such as timber. Forests are vital to the environment because they clean the air we breathe. Forests are also treasured for their beauty.
