Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.

Last summer, when Amanda R of Anaheim Hills, California, was running on a cross-country course with her team, she blacked out. “I got really dizzy,” she says. “I was out for a few minutes.” At first, Amanda thought she was just tired and didn’t think she had a health problem. She did go to the emergency room, where she was fine after tests, but she fainted (昏厥) again several days later as she was talking with her coach. Another doctor guessed that Amanda had blacked out “because we were in heat so much with not enough water and not enough of the right kind of foods”.
Teens often don’t want to stop and take a break or don’t notice when they start to feel bad, doctors say. However, paying attention if you’re not feeling well is important, as Amanda learned.
As a result, Amanda has changed her habits. “I drink a lot more water,” she says. “And put more salt in my diet. I’m eating more balanced meals.” Amanda advises teen athletes to trust their coaches and speak up when they’re not feeling well. “And recognize the difference between when you’re tired and when there’s something really wrong.”
Some people － up to 3 percent of the population － sweat to
o much, even in cold weather. The condition, called hyperhidrosis (多汗), can affect many parts and it often runs in families － hands down from generation to generation.

A man who failed to return more than 700 children’s books to five different libraries in the county was put into prison. Yesterday he was set free after a book publisher agreed to post his bond (担保金) of $1,000. The publisher said, “There’s a story here. This is a man who loves books. He just can’t let go of them. He hasn’t stolen a single book. So what’s the crime? We think that Mr. Brush has a story to tell. We plan to publish his story.”
When asked why he didn’t return the books, Mr. Brush said, “Well, how could I? They became family to me. I was afraid to return them, because I knew that kids or dogs would get hold of these books and chew them up, throw them around, rip the pages, spill soda on them, get jam and jelly on them, and drown them in the toilet.”
He continued, “Books are people, too! They talk to you, they take care of you, and they enrich you with wisdom and humor and love. A book is my guest in my home. How could I kick it out? I repaired torn pages. I dusted them with a soft clean cloth. I turned their pages so they could breathe and get some fresh air.
“Every week I reorganized them on their shelves so they could meet new friends. My books were HAPPY books. You could tell just by looking at them. Now they’re all back in the library, on the lower shelves, on the floors, at the mercy of all those runny-nosed kids. I can hear them calling me! I need to rescue them. Excuse me. I have to go now.”
