'Hands On' - the regular Earth Report programme that gives tips on green enterprise - tours the world in search of innovation. This programme starts in a
laboratory in Belgium where we find that bees arethe latest recruits in the battle against pollution. In Sweden, more animal magic - the sniffer dogs trained to detect mercury. In Bangladesh, sari cloth is being used as a cheap and simple filter to help prevent the spread of cholera. In China, coalbed methane is a peril for miners. It has to be vented safely into the atmosphere. But methane is a greenhouse gas many times more potent than carbon dioxide. Through a new method being tried out in the mining town of Yangquan it's being used to meet household energy needs for 20,000 people.
