We can make shoes from the s_____ of animals.

Trees are useful to man in three very important ways: they provide him with wood and other products；they give him shade；and they help to prevent drought and floods.

Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.

Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal(木炭) or selling wood to the townsman（城市居民）. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

This does not only mean that the villager’s sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.

In 1999, 11-year-old Kevin Stephan was a bat boy for his younger brother's Little League team in Lancaster, New York. It was an early evening in late July. The sun shone at an angle  across the field. The game unfolding in baseball time. Kevin was standing on the grass away from the plate, where another youngster was warming up. Swinging his bat back and forth, giving it all the power an elementary school kid could gather. The boy brought the bat back hard and hit Kevin square in the chest.

His heart stopped.

When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid. Penny Brown hadn't planned to be there that day, but at the last minute, her shift at the hospital had been changed, and she was given the night off. Penny bent over the unconscious boy, his face already starting to turn blue, and administered CPR, breathing into his mouth and administering chest press.

And he came back.

It was a good thing, for a good kid. Kevin wasn't just a volunteer for his brother's baseball team --- he was a Boy Scout, one who went on to achieve Scouting's highest rank, Eagle. He became a volunteer junior firefighter, learning some of the emergency first-aid techniques that had saved his life. He studied hard in school and was saving money for college by working as a dishwasher in a local restaurant. He liked the people, but the work could be hard and pretty routine. Until the afternoon of January 27, 2006.

Kevin, now 17, was working in the kitchen when he heard people screaming, customers in confusion, employees rushing toward a table. He hustled into the main room and saw a woman there, her face turning blue, her hands at her throat. She was choking. Quickly Kevin stepped behind her, wrapped his arms around her and clasped his hands. Then, using skills he'd first learned in Scouts, he pulled suddenly inward and up, once, twice, administering the Heimlich maneuver. The food that was trapped in the woman's throat was freed. The color began to return to her face.

"The food was stuck. I couldn't breathe," she said. She thought she was dying. "I was very frightened.”

Guess who the woman was ? Penny Brown
