Written to a letter of 2108

Dear students of 2108:

Hello! When I wrote this letter, it was in the beautiful coastal city of Qingdao, before 1997. When you received this letter, where are you going to be? I really want to see for myself what Qingdao will look like in a hundred years. I think, you must also want to know what our city is like now, then let's use this letter to talk about it.

In 2008, the population of our planet has exceeded 5 billion. According to statistics, the global population has increased by one billion every twelve years or so. If we grow at this rate, the population of the Earth will reach 10 billion by 2108. Therefore, what kind of city you will live in in the future has become a concern for me and my classmates. Everyone is making various ideas.

The city of the future, although I have not personally visited the classmates, but indirectly in many science fiction or science fiction movies. These are some grotesque places, far from the cities where people live today. In the minds of the students, the appearance and function of the future city are not the same. The future city of science fiction writers is different from the future cities in the eyes of the students. The future cities of scientists are more realistic, such as super cities, high tower cities, arched cities, marine cities, digital cities. , eco-city, sun city, compact city, rural city, cosmic city, three-dimensional city, underground city, etc. In addition, there are group cities, mountain cities, skyscraper cities, submarine cities, desert cities and scattered cities.

Maybe it is because my classmates and I now live in the coastal city of Qingdao, so our favorite city in the future is a marine city. It is built on artificial islands and is surprisingly large in size and size. The ocean city occupies at least 10,000 square kilometers of water, about 100 kilometers from the land. The entire city is on a platform 100 meters above sea level. It will become the home of 10 million people. The ocean city will be attached to the top of 10,000 large columns that are fixed to the bottom of the ocean with concrete stones weighing several million tons. If people are going to travel to a marine city, they can use an airplane or an air-cushioned aircraft with a speed of 115 km/h.

Nowadays, the city we live in pays special attention to environmental protection. I think that the future marine city must also be an eco-friendly city. It will introduce nature into the city and make the city survive like a living body. Every room in the house is sunny, neither heating the stove nor air conditioning. Hot water can be obtained through solar water heaters. In addition, these buildings are still warm in winter and cool in summer, and their temperature is just opposite to the outside world. All the energy in the building does not depend on the external supply, and there is no need for the traditional power station to send electricity. Its power comes from a barrier photocell that can store solar energy, which converts the acquired solar energy into electricity and stores it in the battery. in. When household appliances such as freezers, dryers, washing machines, dishwashers, hair dryers, and even razors need to be powered, the barrier photocells deliver electricity to these household appliances.

How beautiful the future city is! In order to achieve this goal, we will act from now on, establish an environmental protection concept, learn knowledge, master scientific skills, and constantly improve the living environment. By 2108, students will be allowed to live in marine cities and environmentally friendly cities.
