An anti-immigrant environmentalist group is tossing its support behind Planned Parenthood, arguing that its taxpayer funding and overseas abortion aid are needed to curb future refugees and immigrants.

Environmentalist group Negative Population Growth published a report on Tuesday condemning Republican efforts to defund the nation’s largest abortion organizer, as well as efforts to limit abortion coverage in federally subsidized Obamacare plans and the Trump administration’s reinstatement of the Mexico City policy, which prevents foreign aid from going to groups that perform abortions. The group says that abortion and contraceptive services provided by Planned Parenthood are needed to limit population growth in the United States and elsewhere.

“NPG opposes … the ‘defunding’ of Planned Parenthood, or crippling restrictions on the use of federal funding or subsidies to private insurance policy holders for reproductive services,” the report, titled Resurgent Pro-Natalism in the Trump Administration, says. “The Trump Administration’s desire to see both freedom of reproductive choice and federal funding for contraception eliminated must become secondary to the urgent need to slow, halt, and eventually reverse U.S. and world population growth.”

The report also praises Planned Parenthood CEO Cecile Richards for drawing the connection between limiting population growth and environmentalism when she called long-lasting IUDs, which can block fertilization but can also act as an abortifacient by preventing a fertilized egg from attaching to the uterus, the “greenest form of birth control.”

NPG President Donald Mann linked taxpayer funding of abortion overseas and Planned Parenthood, as well as subsidized abortion and contraception coverage, to immigration in a statement accompanying the report. He said any effort to divert money from abortion providers would “ultimately be devastating to our nation” by increasing immigration.

The Southern Poverty Law Center—which has been criticized by conservatives and championed by liberals—has labeled the NPC an “anti-immigrant” group several times, listing it as a “key player” in efforts to link environmentalism, population control, and immigration to advance “white supremacy.”

NPG spokesman Edwin Rubenstein said the SPLC purposefully misconstrues the group’s mission. “They put thousands of these non-profits in the same bucket as overtly racist groups but where is the hard evidence? They have none. They have a way of destroying reputations undeservedly. It’s a very powerful lobby,” he told the Washington Free Beacon. “NPG’s interested in a sustainable economy because economic growth is not a good thing when you’re using resources at a faster rate than they can be replaced naturally. Anything we can do to both reduce the rate of population growth or, ideally, reduce the population itself will reduce the amount of stuff we consume.”

Planned Parenthood did not respond to a request for comment regarding the report or NPG.
