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（审计） and based on environmentally friendly policies，according to the magazine.
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 colorists 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

| Is veg food healthier than non-veg food? I feel this is a very common topic that people speak on．Please give me your opinions on this topic． | |
| Rao 12-18-08 | So far as veg food is concerned, it is also proved to be a healthy and nutritious diet, but has very few items which can provide us with proteins, but if you see non-veg food like eggs, chicken, and many more, such foods have a large content of proteins in them. |
| Sai 12-19-08 | Man basically is herbivorous（食草的）. If we look at the animal kingdom We can see that all the herbivorous animals have the similar dental（牙齿的） structure, which clearly shows that the human being also ought to be vegetarian by birth. It is only the living conditions that make man carnivorous（食肉的）. The vegetarian foods are easily digestible. |
| Santos 12-20-08 | Non-veg food items are better than veg items. A healthy person requires complete diet and veg+ meat makes the diet complete. The only caution that needs to be taken is not to have non-veg items on a daily basis. Once in a week or couple of weeks will be best. |
| Krishna 01-03-09 | When we eat non-veg, we are all veg by nature. The chicken that we eat feeds on grains, the mutton that we eat feeds on grass, and the fish that we eat feeds on simple plants. So non-veg food by logic（逻辑）is better and suited for hauman beings. |
| Khan 01-05-09 | Non-veg food is equally important in our diet as it helps in many ways, especially fish and other seafood as fish contains omega 3 which makes our immune system（免疫系统）stronger. Do you know that most of the veg food put together does not contain as much omega 3 as fish alone contains! |
Bond had walked for only a few minutes when it suddenly occurred to him that he was being followed. There was no evidence for it except a slight headache and a little knowing the people near him but believed in his sixth sense and he at once stopped in front of the shop window he was passing and looked occasionally back along 46th Street. Nothing but a lot of miscellaneous people moving slowly on the sidewalks, mostly on the same side as himself, the side that was back from the sun. There was no sudden movement into a doorway, nobody wiping his face with a handkerchief to avoid recognition, nobody bending down to tie a shoelace.
He went on and turned into the Avenue of the Americans, stopping in the first doorway, the entrance to a woman’s underwear store where a man in a blue suit with his back to him was examining the black lace paints on a particularly realistic-dummy（模型）.
And then something grasped his arm and a voice came, “All right, Limey. Take it easy unless you want lead for lunch,” and he felt something press into his back just above the kidney.
There was a tap as his fist was caught in the other man’s left hand, and at the same time as the contact telegraphed to Bond’s mind that there could have been no gun, there came the well remembered laugh and the lazy voice saying: “No good, James. The angles have got you.”
Bond straightened himself slowly and for a moment he could only gaze into the smiling face of Felix Leiter with blank dis-belief, his built-up tension（紧张）slowly relaxing.
“So you were doing a front tail, you bastard（赝品）,” he finally said.
1. Bond realized that he was being followed by means of _____.
A. his common sense B. his sense of humour C. his sight D. his sixth sense

A. most people on the sidewalks were on the same side as himself
B. no one suddenly turned into a doorway
C. a man was looking into the window of a store
D. no one wiped his face with a handkerchief
3. Why did Bond stop in the doorway to the underwear shop?
A. To see who was following him. B. To look at the man in the blue suit.
C. To avoid the sunshine. D. To look at the underwear.
4. What did the man mean by saying “Take it easy unless you want lead for lunch”?
A. Put up your hands.
B. Don’t move or I’ll shoot you.
C. If you want to have lunch, you must listen to me.
D. You go first slowly and we’ll have lunch together.
5. What is “a front tail”?
A. Pretending to be someone else. B. Following somebody from in front.
C. Following someone from behind. D. Standing in front of a shop window.
