Liechtenstein- It could be straight out of 'The Sound of Music'--but it's not Salzburg. It's the principality of Liechtenstein, the last German-speaking Monarchy in the world. Snuggled between Switzerland and Austria, it's Europe's fourth smallest country, covering an area of only 160 square kilometres. But despite its size, the country is a world leader on environmental issues. By the middle of last century it had passed laws covering water and land conservation and in the early 70s covering air pollution. Recycling Mining Sludge- Skinningrove is a small village on the north-east coast of England. Once there were 86 mines in the region, when Teesside was one of the iron and steel centres of the world. The last of the old mines closed 40 years ago, but still the rivers are stained a reddish colour by ochre, that leeches out of the old mines. It coats vegetation, clogs fish gills and when it feeds into town water supplies, blocks pumps and sewers. China Melting Ice- Perched on the edge of Siberia, Harbin is known as one of China's coldest cities. But things have changed here, as in the rest of China. With a booming economy has come pollution, an overabundance of cars, and rising temperatures. For 24 years Harbin's Ice Lantern Festival and Snow Sculpture Show have brought in tourists from all around the world. In the city's Zhaolin Park, competitors gather for the ice sculpting contest where they're given three days to carve, chip and sculpt. Antarctica Map- At a recent press conference, a joint American and British team of researchers unveiled a new map of Antarctica. The landsat image mosaic of Antarctica, or Lima, is expected to revolutionise research and the public's understanding of the continent. Broadcaster Comes To Aid Of Frogs- This is probably the most poisonous animal in the world--the Golden Poison Frog. But like many species it's under threat of extinction. Fortunately, frogs of all kinds have good friends on their side. Water Technology- It's the sound of life, and it's our most precious asset--water. But in many countries it has also been our most squandered and neglected resource. Now, finding water, making it clean, and protecting it are shaping up as big issues and big money. At a recent exhibition, marketing Israeli products to foreign investors, businesses showed some of the innovative products they've developed to combat water problems. Kenya Glass Kenya's Nairobi National Park, where wild animals roam freely, is also home to Richard Koitumet Ogeli. Every day he travels long distances, trekking through the plains to the rough road that borders the park. It is here, at an extraordinary arts studio, that Richard works. He is a glass blower and is probably the first Masai glass blower in the world.
