Local < 2 fertility rates are swamped by global > 2 rates. Overpopulation is a global problem affecting the US, same as global warming. The US is fast growing in population.

>The US is fast growing in population. No. Google: 'US births per woman'. In the US, that is ~1.7. 2.1 is considered the replacement rate in developed countries. After that, check out: 'world births per woman' Currently (2011) @ 2.41 down from 2.67 in 2000, 3.23 in 1990. Do you expect this trend to suddenly flatten or reverse? In the future, longer life expectancy will likely have a larger impact on population numbers than birth rates. In specific developed countries, I would also expect immigration to be part a large part of growth.

  The U.S. population growth rate is ~.75% per year. Even though the fertility rate is lower than some other industrialized countries, the immigration rate is very high. Global average population growth rate is 1.1%.

  The US population grew by almost 10%, over 27 million, between 2000 to 2010.

    Yes, but not from the birth rate. The US receives well over 1M immigrants per year[1] [1] http://www.pewhispanic.org/files/2005/09/2005-immigration-trends-01.png http://www.pewhispanic.org/files/2005/09/2005-immigration-tr...

This is completely wrong. World population is about 7.2 billion people and growth is slowing. The UN projects it will peak at about 9.1 billion in about 2050, then decline slightly. And the US population isn't fast growing, its projected to reach 438 million by 2050. Most of the US growth will be immigration, which is completely under our control. As for being swamped, lately, in spite of the recent economic downturn, global population growth rates have been lessening by more than demographers expected. All of this can be read with a cursory Google search. My numbers are from the UN, US Census Dept., and Pew Research.

  immigration, which is completely under our control. And yet media reports consistently imply that restricting immigration is both impossible and unethical.

No they aren't. Global population is levelling off faster than people anticiapted and is likely to plateau at 9b in 2050 - a lot of people, to be sure, but far from the Malthusian scenario you seem to be suggesting.
