All over America, there are millions of Americans that are quietly preparing for doomsday. They are turning spare rooms into long-term food storage pantries, they are planting survival gardens, they are converting their homes over to alternative sources of energy, they are taking self-defense courses and they are stocking up on just about anything you can imagine. They are called "preppers", and their numbers have absolutely exploded in recent years. In fact, you might be living next door to one and never even realize it. According to a recent Daily Mail article, there are approximately 3 million preppers in the United States today. Others believe that the true number is significantly higher than that. This movement has become so popular that there are now even television shows being done about preppers. The most popular is probably "Doomsday Preppers" on the National Geographic Channel. This movement is still growing and is not going to go away any time soon.
