Air travel is often cheaper than train because there is no international tax on aviation fuel. In many parts of the world, including the south of England, there are water shortages, whilst golf courses continue to be built. In India women are becoming slum dwellers as the fields they used to farm have been turned into golf courses. Many have then been driven to prostitution to support their families. Golfers, caddies and residents near golf courses can suffer from respiratory diseases.
