Choosing a city to live in?

I guess most people do not take the environment as an important factor when they decide to move into a city. Some of the things they consider are night life, weather, friends, family, cost of living.

However, I think it is also important to take into consideration some environmental factors:

• Traffic. A city with too much traffic can not only waste 1000s of hrs of your lifetime, but also can be harmful for the environment, because cars consume fuel even when idle.
• Flat terrain. In a city with a flat terrain, it is possible to ride a bike. Not only is this good for the environment but also good for one's health and pocket. Also cars are more fuel efficient in flat terrains.
  
• Climate. A city with moderate climate will allow you to drive with the AC off during the summer. And would have minimal usage of both heating and cooling in your home or office.
• Building codes. A city with good building codes would help cut your electricity/heating bill.
• Public transportation. A city with good public transportation would save a lot of energy and would be very good for your pocket.

So I guess everyone living in Arizona and New Mexico would have to move out.
