Let's suppose it is a common day of 2060. Of course, things have changed and life is very different. Trips to the moon are being made every day. Taking a holiday on the moon today is as easy as taking a holiday in Europe in the 2010s. At a number of scenery spot (风景胜地) on the moon, many hotels have been built. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment of the young and old. What are people eating now? People are still eating food. But many foods now come in pill(药片) form, and the food that goes into the pill comes mainly from green plants. Because people in the world today are many more than those about fifty years ago, most of the earth's surface has to be filled. The deserts are irrigated with water and crops are no longer eaten by pets(害虫). 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 using a few computers. People are now largely vegetarians, and they eat only bread, vegetables, and fruit and so on and they don't eat meat or fish. You see, as the number of people increases, the number of animals decreases. So people have to be vegetarians. We are healthier both in our bodies and in our minds, and we know how to deal with all kinds of illnesses. No one has to be ill any more. Such would be our life in 2060.
