The hottest“green”toy in Germany isn't made of organic or recycled materials.This one has a solar panel and only runs if kids remember to insert bright red “energy stones”that power the space station.Germany，a pioneer in many renewable energy initiatives，is also at the forefront of creating environment?friendly toys aimed at making kids think about where energy comes from and how much of it they can use，raising awareness through play.A number of high?tech green toys are on display at this year's Nuremberg toy fair，which runs through Sunday.

Among them，there are hydroelectric?powered(水电动力的)toy cars，and doll houses with wind turbines and rainwater catchers.The bright green “Future Planet”space station features an inner atrium(中庭)with a fan that is powered by a functioning solar cell.Its aim is to get kids to use their imagination about how energy will be created in the future.

Makers and retailers believe such toys will play an increasingly important role in their future—and that of our kids.“Energy is the question of the future and we are definitely thinking about this as we move ahead，”said Judith Schweinitz，a spokeswoman for Playmobil，maker of the solar panel?fitted space station.“It is increasingly being brought into our play concept.”Green toys—which range from those made of sustainable materials to ones like the space station that just raise environmental awareness—make up only a sliver of the $ 84 billion international toy market，but their share is growing，studies indicate.Environmental research firm Earthsense，based in Syracuse，New York，predicts that green toys will account for about $ 1 billion，or 5 percent of U．S.toy sales in the next five years.Parents are smart and they want information about what's in the product.That's what's really driving the market.

“The U．S.Food and Drug Administration(FDA)is considering to put stricter limits over tanning salons(晒黑廊)and wants to ban anyone younger than 18 years of age from using a tanning bed，”an advisory panel(专家团)announced last week.

The panel is calling for tighter controls on the industry such as requiring teenagers to get the approval from their parents before using tanning beds or limiting the use of artificial tanning to a certain age.“Given the absence of any demonstrated benefits，I think it is an obligation for us to ban artificial tanning for those under 18，”said panelist Dr.Michael Olding.

Along with a possible ban for teenagers，the panel also recommended that visible warning labels should be placed either on the tanning machines or in the salons in order to caution tanners of the possible dangers.In addition，the committee decided that stricter regulations and classifications were critical to make the machines safer.At this time the machines are categorized as FDA Class 1 devices，the ones that are least likely to cause harm.In case the FDA decided to change their classification from Class 1 to Class 2，as advised by the panel，the FDA could limit the levels of radiation the machines emit.Class 2 devices include X?ray machines and powered wheelchairs.

Getting a tan，whether from a tanning bed or the sun，increases the risk of developing skin cancer.Last year，the World Health Organization's International Agency for Research on Cancer (IARC)declared tanning beds as “carcinogenic(致癌的)to humans”．It was discovered that young individuals in their teens and 20s who use tanning beds on a regular basis have a 75 per cent higher risk of suffering from melanoma(黑素瘤)，the deadliest form of skin cancer.According to the American Cancer Society，melanoma accounted for nearly 69,000 cases of skin cancer in 2009 and will account for most (about 8,650)of the 11,590 mortality cases due to skin cancer each year.
