　　Monarch without a Kingdom

　　Although its body is about 3 cm long and it only weighs 1 gin, the Monarch butterfly manages to travel 5,000 km each year. It seems to be so fragile, but its long journeys are proof of its amazing ability to survive. This autumn, the Monarch butterfly will once more set out on its journey from the US. It will keep going until it reaches Mexico. It travels these huge distances to escape the cold weather in the north.

　　Before reaching their journeys end they have faced strong winds, rain and snowstorms and they do not all manage to reach their destination. When the winters are really bad, perhaps 70 per cent of them will not survive. Their long journey to Mexico is thought to be one of the most amazing events in the whole of the American continent. When they get there they will stay until the beginning of April, when their internal calendar tells them that it is time to go back. The long journey, with all its dangers, begins again.

　　Greenpeace is campaigning against genetically modified products . The environmental organization recently published a list of 100 species of butterfly in Europe alone which are threatened with extinction.
