Why Cities Are Greener

A lot of environmentalists have a very knee jerk objection to cities. They see that they are more distant from nature than rural communities and conclude from this that they must be unnatural and hence unhealthy for people and the environment. That cities keep people separate from nature, however, is precisely why they are good for the natural environment.

Here's a great article about cities and their environmental impact.

These are my favorite quotes:
"To most people, big, densely-populated cities look like ecological nightmares, wastelands of concrete and garbage and diesel fumes and traffic jams. But, compared to other inhabited places, cities are models of environmental responsibility. By the most significant measures, the greenest community in the United States is New York City, the only American city that approaches environmental standards set elsewhere in the world."

"Moving people closer together reduces the distances between their daily destinations and limits their opportunities for reckless consumption, as well as forcing the majority to live in some of the most inherently energy-efficient residential structures in the world: apartment buildings."

"New York’s highly concentrated population and comprehensive public transit system enable the majority of residents to live without owning automobiles, an unthinkable deprivation almost anywhere else in the US. Some 82% of employed Manhattanites travel to work by public transit, bicycle, or on foot. That’s 10 times the rate for Americans in general, eight times the rate for workers in Los Angeles County, and 16 times the rate for residents of metropolitan Atlanta."

If you think it's easy to get around without a car in any other city, keep in mind that even David Suzuki owns a car.

"I spoke with one energy expert, who, when I asked him to explain why per-capita energy consumption was so much lower in Europe than in the US, said, 'It’s not a secret, and it’s not the result of some miraculous technological breakthrough. It’s because Europeans are more likely to live in dense cities and less likely to own cars.'"

"Urban families live more compactly, do less damage to fragile ecosystems, burn less fuel, enjoy stronger social ties to larger numbers of people, and, most significantly, produce fewer children, since large families have less economic utility in densely settled areas than they do in marginal agricultural areas."
