The effect that urban sprawl has had on people in general would be the fact that taxes are increasingly higher. Urban sprawl can cause increased traffic making work commutes longer and using more gas and creating more pollution (Tox Town, n.d.). There are higher costs for services such as refuse pickup and water supplies. The air quality can diminish and become toxic to people. For example, in my state of Washington, we periodically experience times where the air quality is poor and people who are on oxygen or have other health related problems are advised to not be outside. This is a problem caused by urban sprawl.

　　I believe urban sprawl has caused multitudes of environmental problems. Since people are using more resources than they need, they are undermining the efforts to create sustainability. Further, the pollution that comes with urban sprawl is having effects which support the issue of global warming. I believe something needs to be done to promote smart growth and sustainability. For instance, using subways and buses or living close enough to work to walk will help dramatically. If we take a proactive approach to this problem, over time we may be able to live in an environmentally stable world.
