Twelve years ago,a young traveler named Rhett Butler from San Francisco,California, visited the Sabah rainforest on Malaysian Borneo. In one area of the rainforest,he watched a bird flying through the trees. The beautiful sight lett quite an impression on him. But weeks later,back home, Rhett Butler got the news that trees had been cut down in the area hevisi1ed. That experience led Rhett Butler to begin writing a book about rainforests and threats to their existence. But he did not publish the book. Instead, in 1999, he used his research for the book to create a website,Mongabay. com. His purpose was to inform the public about tropical rainforests. But the subject quickly developed. As a former businessman,he became a respected writer of science and environmental stories. The popularity of Mongabay. com attracted advertisers. Small ads on the site pay for its operations. Mongabay. com has grown and led to other sites. For example,there is a site for children which is called Kids. Mongabay. com. Another one,WildMadangascar. o rg, is allabout the island nation that Rhett Butler calls his favorite place. To keep his website going, he travels around the world on several major trips each year. His working tools are a laptop computer,cameras and sometimes diving equipment. He often calls on experts for information. For example,he interviewed Alison Jolly,a top expert on lemurs  . He interviewed Rodney Jackson,a biologist who established the Snow Leopard Conservancy. Stories like these have made Mongabay a favorite place on the Internet for researchers, students and teachers. In April, Time, com named it one of the fifteen top climate and environment websites in the world. Rhett Butler didn't publish his book about rainforests because  _  .
he didn't want to become a writer the book was not about rainforest protection he wanted to use the information to create a website making websites earned more money than writing books
