Lai, Bei-Yuan is known as Taiwan’s Tree King. Over 30 years ago, he left his family’s successful shipping business and began buying large areas of land in the mountains in Taichung. On the land, he planted a lot of trees---over a quarter of a million of them!   But what made Mr. Lai decide to spend over NT$2 billion buying land to grow trees? Mr. Lai says that the customers he used to serve as part of his day job were all in businesses that polluted the earth. He felt that he needed to do something to restore the earth’s life energy.   The trees Mr.Lai plants are all types that can grow for a thousand years or more! They help hold the soil together and keep water flowing through the earth.   Some of these trees produce very expensive wood. But Mr. Lai has an idea of not letting anyone to cut down his trees, even though he could make a lot of money from it. As long as the Tree King is around, his forest will be safe. * billion 十億 serve 服務 pollute 汙染 soil 土壤
