Passage translation:

　 Man is closed connected to the environment. Our environment provides us with fresh air to breathe, clean water to drink and various vegetables to eat. However, our environment is faced with many dangers. It is seriously polluted with chemical wastes from factories and garbages from the city. Trees are being cut down, large areas of forests are being destroy, and various animals are being hunted and killed. As a result, many kinds of plants and animals are disppearing from the earth.
