There are somewhere between 45,000 and 100，000 of them living in countries like Zambia and Zimbabwe. Theyre not rich and they dont live in expensive houses. There are no roads or schools or hospitals near them. They dont have many material possessions like cars or computers, things that people in the developed world cant do without。 In fact, they have many problems such as unemployment and poverty. On top of this, they also suffer from alcoholism, drinking to forget their problems。 Theyre the San， a tribe of traditional huntergatherers， who used to travel in search of food for their families instead of growing it or keeping animals. They have a culture that is 20,000 years old， but their old way of life is disappearing fast and has nearly gone forever。 So yes, theyre poor, and yes， their lifestyle is not attractive to outsiders， but they do have one thing that certain people in the developed world are very, very interested in and want to have， and that may make them some money. Its called hoodia. BMany countries have basic， common crops that . people plant for food， such as rice or potatoes。 Potatoes are grown in many European countries as well as South America (They originated there!), and rice is a staple food in Asia。 But not all plants are grow just for food; some of them can also be used as medicine. A few examples are garlic, which is said to help with colds or high blood pressure, ginger to help with headaches or toothache, or the magnolia tree which is used in Chinese traditional medicine to treat some forms of cancer and heart disease。 Hoodia, a cactuslike plant, only grows in the area where the San live， and they know where to find it and the best time to use it. They have known about it for centuries and they understand how to use it, but they dont use it for food， and they dont use it to cure disease either. They use it to fight hunger. CIn the old days when the San had to travel in search of food, they and their children sometimes had to go without food for several days。 This was even longer in times of famine or when the rains failed. They ate the hoodia plant when they were starving， to help them survive until they found food， to stop their children from crying， and to give them the strength to continue their search. However, it didnt give them energy like normal food would. Instead， the chemicals in the hoodia plant killed the feeling of hunger and stopped them wanting food。 They didnt know exactly how it worked; the only thing they knew for certain was that it did work. DScientists have now discovered that the plant contains a substance which they have called P57。 This chemical makes the brain believe that the stomach is full and that the body doesnt need food. That is why people in the developed world， especially those in pharmaceutical companies， are extremely interested in this very promising plant. EObesity in the developed world is a huge and growing problem, not only among adults, but increasingly among children。 It has been estimated that up to 50 of people in the developed world are overweight and 20% of these are obese； at the time of writing， for example， 30 of Chinese children were considered to be too heavy for their age。 One cause of obesity is eating too much， too often, and another is eating the wrong kind of food. Our grandparents had the time to prepare simple yet nourishing meals， and they didnt have money to afford expensive food。 They didnt eat as much meat or fatty foods as we do nowadays， and thats one reason why they were slimmer and healthier than their descendants。 Today we have less time to cook， and we have more money, so the easiest thing to do is to buy readymade meals. They may be convenient and taste good, but theyre often high in fat， salt and sugar. Too much of these make people unhealthy and fat. They need to lose weight, and thats where hoodia comes in。 FIt seems to be the perfect solution。 People in the West want to lose weight and hoodia is ideal. Western companies pay for the right to use the secrets of the hoodia plant； by selling these rights to the West， the San make money and can then help themselves. Obese people lose weight and the San people make a profit， so everyone is happy。 Read the first and last sentence ONLY of each paragraph in the reading passage.
