Bill Nye "the Science Guy," once the beloved figure of the popular PBS children’s show, fundraised and gave a talk for Planned Parenthood of South Texas Tuesday in which he renewed calls for population control in response to climate change.

Nye, whose actual, scientific credentials consist of a bachelor’s degree in Mechanical Engineering, focused on climate change in his talk and reportedly discussed “evidence that explosive population growth is a major factor driving it.”

He also praised the nation’s largest abortion provider for efforts to raise the quality of life for women and emphasized that this was one way to address climate change, saying this would lead to “fewer kids.”

“What’s the one thing to do about climate change, if you want to think about the big picture? Raise the standard of living of girls and women,” he said, explaining, “when you raise the standard of living of girls and women, they have fewer kids, and the kids they have are better cared for.”

“The thing that gets me about the time that I grew up in and the time we’re living in now is how fast things have changed, and Planned Parenthood has been here since the very beginning,” he said.

In an interview following the lunch, Nye also mocked abstinence-based sex education, claiming “it’s ineffective. People whose sex education is abstinence often are called 'parents.'”

Prior to the event, the abortion affiliate sold tickets to have lunch with Nye to raise funds.

Nye has been a vocal and radical supporter of abortion and population control recently. His Netflix show "Bill Nye Saves The World," featured a segment discussing the idea that people should be "penalized" for having "extra kids" who could potentially contribute to climate change.

He also argued for abortion in a 2015 video.
