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.
