London used to be “foggy” for the same reason that cities like Beijing or Chongqing are “foggy” today．The “fog” was in fact smog, a mixture of smoke and fog．In other words, it was made by air pollution．In London, some of this pollution came from factories, but much of it came from the coal(煤)that people burnt in their houses to keep warm during the winter．By the 1950s, London’s smog problem had become so bad that the government decided to do something to clean the air．A new law was made and nobody could burn coal in any British city．Within a few years, the air became much cleaner．There were no more “pea-soupers”．

Many Chinese cities now face the same sort of problem with air pollution that London faced 40 or 50 years ago．However, this problem is more difficult for Chinese cities to solve．One reason is that more of the pollution comes from the factories, rather than from coal burnt in people’s houses．If these factories were closed, this would harm the economy and lots of people would lose their jobs．Another reason is that changing from coal to cleaner fuel(燃料), like gas, is quite expensive．

However, the air in many Chinese cities is becoming cleaner and cleaner, as the government and people pay more and more attention to cutting down pollution．As a result, there are fewer “pea-soupers”in Beijing than there used to be．

Life in the twenty-first century

The World Future Society is a group of people from more than 80 countries who are interested in how modern technology is making our world better, and who write reports about how it will change our lives.                                                                                                                                             The things that we will be able to do in the twenty-first century (since the year 2000) should help us live better lives in many ways, at home and at work, in our own country and around the world. Here are just some of them, put into five groups.

People

People may live for up to 120 years and use new technology to help when people go blind, deaf and have other problems. The number of people over a hundred years old could go from 135,000 today to 2.2 million people by 2050. By 2015 people think that 100 million workers will be able to work from home for a company in a different country by using the Internet.

Money

Worldwide e-business will become even more successful with online shops that sell special products for each person, which will be brought to their house the next day.

Environment

The technology for making energy from wind and the Sun is growing very quickly. In the future wind and Sun energy could become much cheaper and many more countries could use it. This would be very useful in poor countries. The air in big cities would also become much cleaner and healthier as a result.

Society and culture

The Internet will help to create more worldwide friendships. Families may spend more time together as people will be able to do 24-hour online banking and shopping.

Technology      

The new science of “nanotechnology” (very small robots or machines) will make all sorts of products smaller and lighter. Very, very small machines could take away rubbish, make things in factories, and help inside the human body by taking away fat. By 2012 people will be able to wear these small machines that look like watches, which will give them lots of information about their body and keep them healthy.
