Input: Consider Input: Article: LONDON ( Reuters)-- Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers. Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying. "Evidence is growing that many animals do not react well to tourists in their backyard," New Scientist magazine said. The immediate effects researchers have noticed are changes in behavior, heart rates, or stress hormone levels but they fear it could get much worse and over the long term "could endanger the survival of the very wildlife they want to see". Although money produced through ecotourism, which has been growing at about 10--30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited and based on environmentally friendly policies, according to the magazine. "The transmission of disease to wildlife, or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding," said Philip Seddon, of the University of Otago in Dunedin, New Zealand. Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by ecotourists are producing smaller babies. Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started. "The animals' welfare should be very important because without them there will be no ecotourism," said Rochelle Constantine of the University of Auckland in New Zealand.

Input: Consider Input: Article: In 1969 I was a young girl working in Toronto. I was from a small town in Ontario and had just moved to the big city about three months earlier. It was one week before Christmas and I was going home on the last streetcar of the evening. I remember looking at my paycheque and asking myself how it was going to endure. At that time in my life I hardly had enough money to exist on. Bread for supper and oatmeal for breakfast was the only way I kept hunger at bay. I got off the streetcar and started walking up the street, when I suddenly noticed a man was running after me. I stopped, turned around, seeing that he was black. I _ , "What do you want?" The man answered in a soft voice, "I am returning your wallet. You left it on the streetcar seat." Because of that man's thoughtfulness, I was allowed the comfort of going home by bus for the summer holidays. Otherwise, I would have stayed alone in my small room with a hog plate. I have never been so ashamed of myself, and that poor, kind man had to walk, who knows how far, home. I recognized immediately that this was wrong of me and it changed my ways forever.

Input: Consider Input: Article: Last Friday, after doing all the family shopping in town I wanted a rest before catching the train, so I bought a newspaper and some chocolate and went into the station coffee shop. It was a cheap self-service place with long table to keep a place and went to get a cup of coffee. When I came back with the coffee, there was someone in the next seat. It was one of those wild-looking boys, with dark glasses and old clothes, and his hair was colored bright red at the front. What did surprise me was that he'd started to eat my chocolate. I was rather uneasy about him, but I didn't want to make more trouble. I just looked down at the front page of the newspaper, tasted my coffee and took a bit of chocolate. The boy looked at me closely. Then he took a second piece of chocolate. I could hardly believe it. Still I didn't say anything to him. When he took a third piece, I felt angrier. I thought, well, I shall have the last piece. "And I got it." The boy gave me a strange look, and then stood up. As he left he shouted out, "There is something wrong with the woman," Everybody looked at me, but it was worse then I finished my coffee and got ready to leave. My face turned red when I knew I'd made a mistake. I wasn't my chocolate that I had eaten. There was mine, just under my newspaper.
