     LONDON ( Reuters) -Ecotourism (生态旅游) is  causing  a  lot

of damage to wildlife and may be endangering the survival(生存) of

the very animals people are flocking to see,according to researchers.

        Biologists and conservationists (自然环境持论者) are worried

because polar bears,dolphins, penguins and other creatures are

getting stressed and losing weight and some are dying.

       "Evidence (证据) 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 govemments fear not all projects

are audited (审查) and based on environmentally friendly policies,

according to the magazine.

      "Transmission (传播) 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 bottle-neck 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

that 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.
