A new study by a renowned physicist ties the immigration-reform bill in Congress to global warming, warning that the consequent increase in U.S. population poses an even greater threat to the planet’s survival.

Albert A. Bartlett, a Harvard Ph.D. and professor emeritus of physics at the University of Colorado, explains each person in the U.S. is responsible, directly or indirectly, for emission of 23.8 tons of greenhouse gases annually.

“So if we are serious about reduction of U.S. emission of greenhouse gases in the hope of slowing or stopping global warming, then it is imperative that the first thing we do is to stop the U.S. population growth,” Bartlett declared.

Bartlett emphasized that since immigration – most of it legal – is estimated to account for about three quarters of the present annual increase in the U.S. population, it is essential “we do everything possible to halt U.S. population growth quickly.”

Bartlett, a member of the board of advisers of a non-profit group called Population-Environment BALANCE, claims U.S. population growth “violates the laws of sustainability,” which include:

  • Population growth and/or growth in the rates of consumption of resources cannot be sustained.

  • The larger the population and/or the larger the rate of consumption of resources, the more difficult it will be to transform the population to the condition of sustainability.

  • A society which has to import people to do its daily work is not sustainable.

Bartlett further argues mass immigration also increases the nation’s birth rate. According to the Center for Immigration Studies, immigration’s annual contribution to population growth reaches nearly 90 percent if children born to recent immigrants are counted.

Bartlett emphasized efforts at improving efficiency in energy use cannot compensate for continued population growth.

“If there is no end to population growth in the U.S., it is unlikely that there will ever be a decrease in the annual emissions of global warming greenhouse gases by the United States.”

A think tank in another of the leading developed nations, the UK, expressed a similar view in a report it issued this month urging Britons to have fewer children in order to help save the world from global warming.

“The greatest thing anyone in Britain could do to help the future of the planet,” said John Guillebaud, co-chairman of Optimum Population Trust, “would be to have one less child.”
