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

Dear Seth,

You’re only three years old, and at this point in your life you can’t read, much less understand what I’m going to try to tell you in this letter. But someday, when you’re ready, I hope you will find some wisdom and value in what I share with you.

Life can be cruel

    1.   They’ll tease you or try to hurt you because you’re different.

There’s not much you can do except learn to deal with them, and learn to choose friends who are kind to you and who make you feel good about yourself. When you find friends like this, treasure them, spend time with them and love them.

Be open to life anyway

Yes, you’ll find cruelty and suffering in your journey through life, but don’t let that close you to new things. Don’t retreat from life, don’t hide or wall yourself off. 2. 

Life isn’t a competition

You will meet many people who will try to do better than you, in school , in college, at work. To them, life is a competition.

But here’s the secret: life isn’t a competition.  3.   Learn to enjoy the journey and make it a journey of happiness, of constant learning, of continual improvement, of love.

4. 

If there’s a single word you should live your life by, it should be this: love. It might sound corny, I know, but trust me, there’s no better rule in life.

Love not only your loved ones, but your neighbors, your co-workers, strangers, your brothers and sisters in humanity. And most of all, love yourself and learn to love yourself for who you are.

    5.  You are starting out on an unknown, tiring, scary, but ultimately incredibly wonderful journey, and always remember I will be there for you when I can.

Love,

Your Dad

A. Be open to new things, new experiences, new people.

B. It's a journey.

C. Life is full of love

D. Last, think that you are a wonderful human being.

E. Finally, know that I love you and always will.

F. There will be people in your life who won't be very nice.

G. Love should be your rule
