I think you mean that the rate of increase is decreasing. Otherwise, where did that extra 175 billion Americans come from? I remember when cities were neatly contained within city limits and the space between was filled with farms. I have seen the change to cities that spill over into the countryside and spead subdivision until they run together. It is mostly east of the Mississippi, but urban sprawl is not unknown even in the west.

I did not mention global populations, or growth on other continents. The important facts here are: 125 million in 1933 and 300 million in 2006. Simple arithmetic.

For instance, because of revolutionary new agricultural techniques, food is much, much cheaper today in real dollars than at any other point in history -- heck, in the United States one of our biggest health problems is that the poor are too fat. Imagine describing that problem to anyone from any century before the 20th.

When we are hit by real catastrophic disasters we pretty much don't see them coming, with the possible exception of major wars. Humans are incredibly good at adapting to changes in our environment and are generally able to improve things.
