Let us suppose it is now about A.D.2060.Let’s make believe it is about sixty years from now. Of course, things have ch0?anged and life is very different. Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air conditioned, naturally. In order that every one can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of young and old. What are people eating now? People are still eating food. They haven’t yet started to use supply of energy directly as electrical current or nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants. Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated(灌溉)with water and crops are no longer destroyed by pests. The harvest is always good. Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
