What was the impact of the September 11 2001 terrorist attacks?

In the United States, the immediate impact was of course the Horror of what had just happened coupled with the unity that it brought to the entire population. The attacks also caused a temporary surge of church attendees which could be viewed as a positive side affect to a horrible tragedy. One of the negative side effects were the economic losses the events of September 11th caused. Many, many people lost their jobs as a result of a downturn in the economy after the terrorist attacks. Negative health effects were also a factor. For those near ground zero in New York or at any of the other crash sites, the debris and dust from the collapse of the towers could have and did cause significant breathing problems. The bigger impact was probably the emotional distress the attacks caused though. Americans, as well as people world wide, mourned for the tragic loss of so many innocent lives.
