input:  Now, answer this question: Read the following article and answer the question. Article: Monty Hempel is a professor of environmental sciences at Redlands University in California. He studies ecological literacy--or ecoliteracy, for short. Ecoliteracy is the ability to think about and understand the natural processes that make life possible. Monty Hempel says ecoliteracy gives people knowledge about environmental problems. But he says it does not always work to get them to change their behavior. Mr. Hempel wrote part of the Worldwatch Institute's latest State of the World report. He says in his article, "Some people think that ecoliteracy is just a green form of science literacy. And what I have tried to ask is whether that's enough. In other words, what an ecologically-literate person needs to know might include things like the cycles and the flows, the energy systems, all of those kind of things that we would call the science of ecology. " "That doesn't seem to lead to action to protect our environment--to protect our life-support system to the level that we need to. Just because we know a lot about the environment doesn't mean that we actually act to save it. After all, actions speak louder than knowledge. " He adds that people may not be very worried about environmental problems if they seem far away. "Some people call it psychological distance. A lot of climate issues are worse in the Arctic and most of us don't spend time in the Arctic. And so, there's a certain distance. But there's also a distance that's happening in the world as it urbanizes--people spending more time in front of screens and less time out in nature. We become, if you will, disconnected from the natural systems that used to be the key to success for a human being. " To help children discover the wonders of nature, he adds that children should learn about nature in school. But he also points out we have a high mountain for people to climb from knowledge to action. Question: What is especially important for environment protection in Mr. Hempel's opinion? Answer:
A:
output: Action.

input:  Now, answer this question: Read the following article and answer the question. Article: Housing Price in China has always aroused heated discussion among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8, 000 yuan per square metre, while in China, it is even higher than that in the United States. "This shows that there are some bubbles  in Chinese real estate  market," the International Finance News reported. Although the average price of residential houses in the United States, after changed to RMB, is about 8, 000 yuan per square metre, the houses in the US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If the US property developers sell their houses according to the building area, then the housing price will be even lower than 8, 000 yuan per square metre. In most big Chinese cities, such as Beijing, Shanghai and Shenzhen, houses are sold at a price even higher than those in the US. The high housing price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses cannot be compared with houses in the US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people's average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in the US? At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. Meanwhile, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple...

The problem of high housing price in China and possible solutions to it.
