When the Census Bureau released its new population projections last month, most of the media focused on the country's changing racial composition. But this was almost certainly not the most important finding. The projections show that the U.S. population will grow by 135 million in just 42 years -- a 44 percent increase. Such growth would have profound implications for our environment and quality of life. Most of the increase would be a direct result of one federal policy -- immigration. If we reduced the level of immigration, the projections would be much lower. The question we have to ask ourselves is: Do we want to be a much more densely settled country?
