Snow

Mike Bloomberg, Mayor of New York, has said he is "extremely dissatisfied" with the city's attempts to clean up the snow that has recently fallen. Although streets in the parts of Manhattan crowded with residences and businesses may have been cleared earlier than other streets, there is really no good place to put snow when you are shoveling streets and sidewalks where almost every single square sqaurefoot is so important to so many people that it becomes important to the work of the city. Because there is no good place to put snow in the most important part of the city, it takes a lot of workers and machines to get rid of the snow, either moving the snow quickly to outliying areas of the city or to less crowded areas of Manhattan (like parks.) Because it takes so many workers and machines to clean Manhattan, there are fewer workers and machines who can work in other parts of the city. Because there are fewer workers and machines who can work in other parts of the city, there can be delays clearing the streets in those parts of the city.
My only point in this is to present an arguement that snow-removal is a negative consequence of density. That being said, I do not think that snow on the streets is the most important concern facing people in communitiies like New York in America and around the world.
