Whenever I look at hong kong on google earth, I see a lot of empty green space that tall buildings could be built on.  I also see an area in the north that isn&#x27;t really dense, large open sports areas and green areas on the south island.  HK the territory seems to be much larger than HK the city and it smells suspicious that prices are high but land is not being used.<p>And don&#x27;t say, we need parks!  I&#x27;m fairly certain that large amounts of that parkland is unused because you need to hike in pretty deep to enjoy it.  And highrises can be built on mountains.
