Good number of conspiracy theorists are. Unfortunately the Pope's conduct isn't helping matters.
From “Ecoscience,” by John P. Holdren, Director of the White House Office of Science and Technology Policy, Assistant to the President for Science and Technology, and Co-Chair of the President’s Council of Advisors on Science and Technology --
“Individual rights must be balanced against the power of the government to control human reproduction… Where the society has a “compelling, subordinating interest” in regulating population size, the right of the individual may be curtailed.
Indeed, it has been concluded that compulsory population-control laws, even including laws requiring compulsory abortion, could be sustained under the existing Constitution if the population crisis became sufficiently severe to endanger the society.”
Sam Keen, closing plenary session at Michail Gorbachev’s 1995 Global Conference in San Francisco: “We must speak far more clearly about sexuality, about contraception, about abortion, about the values that control the population, because the ecological crisis, in short, is the population crisis. Cut the population by 90 percent and there aren’t enough people left to do a great deal of ecological damage.”
Professor John Schnellnhuber, founding director of the Postdam Institute for Climate Impact Research: “In a very cynical way, [global warming is] a triumph for science because at last we have stabilized something –- namely the estimates for the carrying capacity of the planet, namely below 1 billion people.” Schnellnhuber was one of three presenters at the June 18, 2015, release of Pope Francis’s encyclical on the environment.
