I asked which causes more pollution, a dense urban center, or a sprawling suburb on Yahoo! Answers. I was surprised as to how many people said urban centers! Why do they think that? Aren't dense urban centers a lot better for the environment (Yes, I've come a long way since my suburb-loving days)?!?!?! In an urban area, you don't have to drive everywhere like you do in the suburbs. You can walk, ride a bike, take a bus, taxi, train, subway, etc.! Some one said that the buses, taxis, trains, etc. increase pollution. But because of the buses, taxis, trains, etc., aren't there less cars per capita? Also, because urban centers are dense, less land is used. Suburbs use WAY more land and you have to drive everywhere. That also causes traffic. Plus, doesn't it take less energy to heat an urban apartment unit that it does a suburban house?
I'm worried that it turns out dense urban centers are worse for the environment than suburbs!
In Atlanta, the answer would be sprawling suburbs, or more specifically, the number of them.
Atlanta's city population is just hovering around 450,000 (est). When you include the metro area, it's just over 5 million. Many of those people work intown during the day, and leave at 5pm. Or they cut through the city as they travel from the suburb where they live to the suburb on the opposite side of the metro area where they work (they're famous for doing that here). All those cars going all those miles spit out tons of smog. We've even had more "smog alert" days than L.A. in some summer months.
Having sprawling suburbs that extend in all directions isn't good for air quality, period.
Of course, in the last week, Atlanta is one of the cities that doesn't even HAVE gas, so the air is getting visibly cleaner and a lot of folks stay at home to conserve it since 9 out of 10 gas stations don't even have gas at all lately.
Id say theyre about equal. Dense urban centers usually have more people, therefore more energy used. Suburbs may have more cars, but also lack the amount of trains, buses, abundant taxis, etc. Also, in dense urban centers, some cities never experience a slowdown (ie NYC, etc), whereas the suburbs usually shut down for the night.

Uh Steve, the question asked on a "per capita basis".
Public transit is more efficient in terms of fuel used than a car containing a single passenger. Additionally, miles traveled per capita in dense cities tend to be lower than in surban sprawl. Furthermore, as the average square footage of residences in urban areas are smaller and often share common walls and floors (condos, apt), the amount of energy required to heat or cool them is less than in an area with predominantly single-family homes (suburbs).
Let's expand this: Do multiple major cities create more pollution and create a large footprint on the environment than just one mega city. Is the mega city more efficient since the rest of the state can be used for farming (or in West Texas' case, ranching). For example Chicago vs. the three (or four) major cities in the eastern half of Texas. Is Chicago more efficient since it organizes the state's population in a smaller footprint than having multiple major cities (such as Texas) and more environmentally-friendly since it cuts down on business trips because the majority of the state's economic activity is located geographically close together (think of the business flights between Houston, DFW, San Antonio, and Austin vs. driving around Chicagoland)?
Uh Steve, the question asked on a "per capita basis".
Shhhh. I knew that, man, I knew that!
Anyways, I'd like to change my vote to "sprawling suburb" because, well, per capita (DOH!!!!!) it causes more pollution than a dense urban center.
