China official says air pollution rules too lax Published on Nov 11, 2011 BEIJING (REUTERS) - China's air pollution standards are too lax, a senior environment official said in comments published on Friday, the highest level comment following complaints that authorities are understating the extent of smog that often envelops Beijing. The level of air pollution in the capital varies, depending on winds. But in recent weeks, a cocktail of smokestack emissions, vehicle exhaust, dust and aerosols have blanketed the city in a pungent, beige shroud for days on end, prompting residents to denounce official readings of 'slight' pollution as a gross undercount. A Vice Minister of Environmental Protection, Zhang Lijun, appeared to agree in comments published by the official People's Daily. 'Currently, the air quality in our cities is quite poor, and there's some gap with the air quality guidelines laid down by the World Health Organisation,' Mr Zhang told a meeting in Beijing on Thursday. 7 natural wonders of the world set to be unveiled Published on Nov 11, 2011 GENEVA (AFP) - The Dead Sea, Vietnam's Halong Bay and Australia's Great Barrier Reef are among 28 contenders to be crowned among the world's new seven wonders of nature on Friday.

Most eco-friendly tours in Korea Wed Nov 9 12:42pm Travel and conserve: Dodge bats and photograph salt farms on these eco trips Becoming a tourist hot spot may mean fame and money for the locale, but it can often bring destruction to the beauty that prompts people to go there in the first place. While eco-friendly tourism has been gaining popularity around the world and organizations such as the International Eco-Tourism Society have been around since the early 1990s, environmentally friendly tourism in Korea is only a recent development. According to Good Travel, an environmentally responsible travel agency in Seoul, eco-tourism has is becoming more and more popular within Korea. Here are some the most ecologically interesting tours in Korea that are also focused on conservation. 1. Baengyong Cave (백룡동굴) What was that mnemonic memorization method again? Approximately 4.5 hours from Seoul by car, Baengyong Cave is one of Korea's officially recognized National Treasures, and is one of the most interesting eco-tours offered in the country. The "tour" is more of a hands-on caving experience, with every tourist required to don bright jumpsuits and headlights before embarking on the 90-minute crawl through the 1,800-meter-long limestone cave system. Originally only accessible by boat, you can now reach the cave via stairs built along the cliff to the mouth of the cave, which overlooks Dong-gang, or the East River. One can only tour the caves when accompanied by official local guides, who are very fatherly and will explain every single stalactite and stalagmite on the way if you let them. For preservation purposes, no photography (and only the most minimal light) is allowed inside the cave, and maximum occupancy is 20 people at a time. Beware the bats.

Jeungdo (증도) Where being slow is a virtue. Of the 10 Korean cities that have been named "slow cities" as of 2011, the small island of Jeungdo is perhaps the most visually stunning, with its beautiful salt farms and mudflats. With the opening of a bridge connecting the island to the mainland, Jeungdo has seen a significant increase in tourism, and residents are trying to make it as eco-friendly as possible. Visitors are shuttled around in electric cars and almost all stores on the island do not sell cigarettes as the entire island aims to be completely smoke-free in the near future. Pensions and lodging houses also provide bicycles to visitors for free. The island even has its own local eco-travel agency that handles the tours of the local wildlife and wetlands. The island is located about 3.5 hours from Seoul by car.
