Obviously if we were experiencing a declining birth vs. death rate that could be a problem. However, we are not. According to CIA World Factbook: Population growth rate:
Definition Field Listing
0.92% (2005 est.)
Birth rate:
Definition Field Listing Rank Order
14.14 births/1,000 population (2005 est.)
Death rate:
Definition Field Listing Rank Order
8.25 deaths/1,000 population (2005 est.)

So, I repeat, what do we need them for?

Hate to pop your bubble. But it is all those anchor babies who are pushing up the birthrate in the USA.
