Nowadays the population density of urbanized area in Beijing is 1.7 times as much as New York ,which is said to be 15,000 persons per kilometer square,while the figure in London is about 5000 persons per kilometer square and Paris,8,000 persons per kilometer square.we can draw the conclusion from this that the large difference between Beijing and other world metropolises is still existing there.further more,beijing is a city heavily short of water.overworking on exploiting groundwater over the years to 1000 kilometer squares' land surrounding the downtown area has caused serious pollution problems.
for a long time in the past,we've been so wrong that we only cherish those palaces ,famous temples,the curiosities ,and tradional chinese painting and so on,but blinded to see those ancient civilians' family houses and treat them as ancient cultural relics.usually,we could only see those highlighted city's symbols,which are marked as city's culture protection relics.
But on the other hand,we have to admit that we're ignorant about how to protect the whole historic atomsphere here to the Beijing city.on thinking about city's economic growth,on caring about how to elevate the people's accommodation conditions,on the necessity to attract real estate companys invest on building up beijing,on alleviating such a serious city's transportation problems,we have thousands of reasons to support us to pull down those narrow alleys and those old houses which have not been repaired for many years since they are retarding beijing's development.
