【正文】 try ing to save grey whales and sea otters from oil pollution off California。 manatees from being chopped up by speedboat propellers in Florida39。s waterways。 Amazon dolphins from extermination. We have other tasks too, which I can39。t go into now. The six youngsters sailing with Sea Shepherd, all keen conservationists, will make a valuable contribution. But they39。ll also have to continue their school studies ... Someone in the audience groaned. Ben grinned broadly. Thank you for listening, ladies and gentlemen. Wish us luck! Loud applause. Then he answered lastminute questions from journalists. The audienceclad once more in raincoats, and clutching umbrellasbegan to file out. Parents hugged their children, whom they wouldn39。t see again for twelve months, and gave good advice that would probably be fotten or ignored. There were some tears. Neither Gary39。s nor Susan39。s parents were present. They had already said their goodbyes at home and were glad to be spared emotional partings aboard Sea Shepherd. By now the lecture hall was empty except for six young people, eyeing each other somewhat warily, and the three teachers responsible for daily lessons. Bellingham greeted them. Wele to the team. I know we39。re going to get along fine ... His next words were drowned by a sudden blast from Sea Shepherd39。s horn. Almost imperceptibly the ship started to move. Ben39。s steady gaze rested on the group. Well ... this is it. 2. Shipmates After the lecture, a tall, ferretfaced man had pushed people aside to be first down the gangway. He didn39。t look like someone much concerned with conservation. He wasn39。t. Sploshing through puddles, he hurried to a phone box on the quay. He dialled a number. His boss would find the report very interesting. Waving parents watched Sea Shepherd glide away between lines of moored vessels, like a guard of honour. Her bright white hull shone luminously against sea and sky, both the same shade of grey. The teeming rain had stopped. Leaning on the ship39。sr pupil. But Vanessa did well too. When the English lesson came it was Susan39。s turn to shine. She warmed a little to Miss Mimpriss after her praise. Peter Stokes, a dominoes fanatic, taught maths. Norman proved brilliant at the subject. A real genius, Gary thought admiringly. Then geography and history master Geoffrey Baggalley took over. He had once been a physical training instructor and it showed. As he talked, he walked up and down and waved his arms as if doing exercises. Mr. Baggalley caught Susan giggling, but Gary put him in a good mood again by answering all the geography questions correctly. At lunch the unsupervised teenagers were rather noisy, cracking jokes about their teachers. It was harmless fun among newfound friends. Only Darren remained remote, cut off from the lively talk. N ow and then Susan glanced in his direction. He seemed unhappy rather than disgruntled, and she felt sorry for him. Once, their eyes met. Susan couldn39。t be sure, but she thought she saw a slight response before he looked down. A quick breath of fresh air, then the youngsters returned to the lecture hall. Ben Bellingham was waiting for them. Please take your seats in the front row. OK, who cares about conservation? Hands up. Everybody reacted. Bellingham pointed to Vanessa. Why? he demanded. Vanessa opened her mouth in surprise. Er ... The naturalist repeated his question, more gently. Why, Vanessa? Why should you care what happens in Africa, the Amazon, the Antarctic or anywhere else that isn39。t your home? What39。s it got to do with you? He nodded encouragingly. Well? Vanessa stuc k out her chin. Animals have as much right to be on earth as we have. More they were here first. And if we39。re the most intelligent creatures, the only ones that are moral, it39。s our duty to look after the environment. Besides, nobody owns the world. All living things are part of nature. So in a way nature owns us ... Blushing, Vanessa tailed off. Without thinking, Susan started to clap. Bellingham: Bravo! You convinced meand at least one other person. Now Susan went pink. Walking along the row, Bellingham added: Anybody else want to speak up for conservation? Yes, Gary. Well, Mr. Bellingham, I was just wondering about the Amazon. The way the trees are being cut downfifty thousand acres a day. Don39。t half of all plant and animal species live there? The naturalist leaned towards him. Quite right. Oh, and call me Ben. Gary went on: I39。ve read that a lot of industry, agriculture and medicine is based on jungle productsrubber, coffee, bananas, quinine and so on. Also that the Amazon is a botanical treasure house we39。ve barely begun to explore. It needs to be protected for everyone39。s sake. Another thingpeople are upsetting the world climate by felling those trees ... Bellingham chipped in. Right again, Gary. But the situation is even worse than that, I39。m afraid, as you39。ll see for yourselve s on this trip. Norman put his hand up. No one has mentioned the gene pool. If the number of species keeps falling, the pla may not be able to evolve to meet changing conditionsand life could die out. Ben rubbed his chin. Certainly done your natural history homework, haven39。t you? He strode to the table behind him, on which stood a glass jar. Turning, he said: I think you and I agree conservation is worthwhile. There was a loud murmur of assent. Bellingham picked up the jar, full of cloudy liquid. Something was floating in it. Know what this is? He unscrewed the lid and, taking a pair of tweezers from his shirt pocket, fished out the mysterious object. Open your hand, he said to Susan. She squealed as he dropped what he was holding into her palm. Slimy and spotted ...
