    Dieting to lose weight has become very popular in recent years. People have become more health conscious and try to take better care of their bodies by eating more healthily and exercising more regularly to lose any unnecessary fat that they may have.

    Not only are people being more careful about what they eat, they are also concerned with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so-called "plastic" fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients(营养成分) in a quiet restaurant with a more leisurely atmosphere. At home, they also try to take enough time to eat a relaxed dinner without phone or TV interruptions.

    While dieting may be viewed as beneficial, it has also become a serious problem for Americans, particularly for young women. Dieting for them has actually become a psychological addiction. They eat so little that they can lose as much as fifty percent of their total body weight, and although they look like skeletons, they still insist that they are fat.

    The current wave of exercising, dieting and the problems produced have caused many organizations to begin educating the public. Many schools, hospitals, health organizations, newspapers and magazines, for example, are offering classed, printing booklet articles and so on, to inform the public of the way to exercise and diet, of the dangers of dieting too rapidly, and of the places people can go for medical help if they find themselves on the road to "diet addiction".

    Although the idea of "zero emission net carbon-positive, sustainable (可持续)" development was promoted worldwide, most cities are at a loss what to do or even some have objected to it. But in Liuzhou, a city in southern China, attitudes could not be more different.

    The Liuzhou Municipality Urban Planning Bureau has signed up Italian architect Stefano Boeri, the father of the forest city movement, to build a self-contained community for up to 30, 000 people. He is the go-to man for such projects thanks to the success of his "vertical forests", two residential (住宅的) towers. Completed in 2014, they remove up to 17.5 tons of soot (煤烟) from the air each year, and a year later one of them was named Best Tall Building Worldwide.

    The Liuzhou project is a much more ambitious undertaking, however. Its homes, hospitals, hotels, schools and offices will be built on a 340-acre site in what Boeri calls the first attempt to create an "urban environment that is really trying to find a balance with nature". Its 100 species of plant life are expected to absorb almost 10, 000 tons of carbon dioxide and 57 tons of pollutants per year, while at the same time producing 900 tons of life-giving oxygen.

    Although the architects haven't published the cost of the forest city, the Milan towers cost only five percent more than traditional skyscrapers.

    The construction of his forest city at Liuzhou is set to begin in 2020, and there is still a great deal of planning and research required before a projected completion date can be set. However, Boeri remains optimistic about the project and has confidence in the soundness of his vision: "I really think that bringing forests into the city is a way to deal with global warming."

    Naturalist John Muir called the Marin County woods named for him "the best tree-lover's monument that could possibly be found in all the forests of the world."

    Located only 11 miles north of the Golden Gate Bridge near San Francisco, California, USA. Muir Woods puts some of nature's most huge creations within reach of little feet, hands, and imaginations.

    "Muir Woods is home to a small forest of redwood trees that reach to the sky," says David Shaw of the Golden Gate National Parks Conservancy. "Redwoods grow taller than any other tree species in the world. The average age of the redwoods here ranges from 400 to 800 years old and many ancient specimens have been around for more than a thousand years."

    William Kent, the man who donated the 295 acres to create the Muir monument, grew up in Marin and played in similar redwood forests. That childhood experience inspired him to save the redwoods as an adult.

    "Young people can learn about young William Kent when they visit here," says ranger(护林员) Timothy Jordan. "Kent's early connection with nature developed his love of the outdoors. As an adult, he witnessed the destruction of many Bay Area redwood forests. This, with the writings of John Muir, inspired Kent's conservationism."

    Walking (and playing)in, on, and around the redwoods will help kids understand why young Kent was so fascinated(深深吸引) by the trees. Ranger Jordan encourages children to lie down and look up at the treetops, hug a redwood tree, and start a nature journal like John Muir.

    "Have kids find a redwood spray(小树枝)the same age as them, count the rings in trees, and sit inside of a hollow redwood tree on Fern Creek." he advises.

    After all the interaction, the kids just may be ready to rest. Take this time to "be quiet and listen to the sounds of the forest," says Shaw. "Encourage kids to think about how these trees have stood quietly through year after year of rain, sun, and sometimes even snow."

Kelli Boehle says her son Nik was an amazing and caring person. Nik was diagnosed(诊断) with cancer in 2008 when he was 17. He passed away in 2012. But Nik's kindness and generosity have lived on long after his death.

After he was diagnosed and started treatment, Nik was granted (给予) a wish experience from the Make-A-Wish Foundation. "For just this period of time, we didn't think about cancer, "Kelli Boehle said. "All we thought about was enjoying our time together."

In 2009, Nik met another young man Nate, who was also going through cancer treatment. He'd been diagnosed a month after turning 18, and Nik learned he was too old to qualify for a wish. The night before Nik passed away, he asked his mother to help ensure that young adults fighting cancer could have their wishes come true too. 

"It was like a seed he planted that just wouldn't stop coming into my mind, " she said. In 2012, Kelli Boehle started Nik's Wish. The nonprofit grants wishes to young adults between the ages of 18 and 24 who are battling cancer. Nate was the organization's first wish recipient. "It's meant to bring them joy and know that they're loved and that we're fighting for them, too, "Kelli Boehle said. 

Recently, 19-year-old Jordan Morrow received her wish to attend a Taylor Swift concert as part of a trip to Los Angeles. For Morrow, who has spent the last year battling brain cancer, going to the concert has done more than lift her spirits. "I think it's something to get me through whatever comes my way, "she said. "And I'm thankful for Nik's Wish for that. "

In the 11 years since Nik passed away, the organization has granted more than 300 wishes across more than 30 states. In the beginning, Kelli Boehle says she wasn't sure she could be a wish maker and work closely with the young adults. But now, it's her favorite thing to do.
