This, however, is not sustainable growth pattern, especially when China has the world’s largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora(大移居)when replaced rural communities are forced into the cities.
On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.
The concept is already practiced at the grassroot level. Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It’s common to see organic “hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translate to tangible (= practical) benefits, such as safe, nutritious vegetables, a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there’re fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit --- all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are doing.
Although people like Zhang are still rare and the greening of roof space with vegetables and fruit takes skill and energy, with more positive media exposure and advanced technology there is the prospect that garden city will become common practice in the near future. By then, cities will no longer look so gray when seen from the satellites.

Scientific experts from around the world are genuinely predicting that 3 years from now, all life on Earth could well finish. Some are saying it’ll be humans that set it off. Others believe that a natural phenomenon will be the cause. And the religious folks are saying it’ll be God himself who presses the stop button... Seven reasons are going about why the world will end in 2012 and netizens have started a discussion in the forum.
1.Mayan Calendar
The first mob to predict 2012 as the end of the world were the Mayans, a bloodthirsty race that were good at two things: Building highly accurate astrological(占星术的)equipment out of stone and sacrificing virgins.
Thousands of years ago they managed to calculate the length of the lunar moon as 329.53020 days, only 34 seconds out. The Mayan calendar predicts that the Earth will end on December 21, 2012. Given that they were pretty close to the mark with the lunar cycle, it’s likely they’ve got the end of the world right as well.
2. Sun Storms
Solar experts from around the world monitoring the sun have made an extremely discovery: our sun is a bit of conflict. The energy output of the sun is, like most things in nature, cyclic (循环的), and it’s supposed to be in the middle of a period of relative stability. However, recent solar storms have been bombarding the Earth with so much radiation energy, and it’s been knocking out power grids and destroying satellites. This activity is predicted to get worse, and calculations suggest it will reach its deadly peak sometime in 2012.
