　　LANDMINES KILL OR BADLY INJURE around 26,000 people every year. That is one person every 20 minutes. What is worse is that they keep causing damage for decades after wars have ended. There are about 100 million landmines buried just beneath the surface of the ground in 60 countries. Most of the victims are innocent people - women, children, farmers - who happen to step on them as they go about their daily lives.

　　We seem to be losing the fight against landmines. While, every year, about 100,000 landmines are removed, 2,000,000 more are buried in the ground. Removing them is very slow and dangerous work that must be done by hand. Someone has to use a metal detector to find the mines. This is very inaccurate as the metal detector finds all metal objects, not just the mines, and it does not find new types of mine which are covered in plastic. Then he or she has to dig the mine out without setting it off. Using this method it could take centuries to rid the world of landmines.
