Bill Nye “the Science Guy” did exactly what scientists are supposed to do this week — ask questions — and people are blasting him for it.

The engineer-turned-comedian-turned-TV host has sparked widespread outrage on social media thanks to an idea he proposed Tuesday on his new Netflix series, “Bill Nye Saves the World.”

During a panel discussion, the 61-year-old Cornell grad asked: “Should we have policies that penalize people for having extra kids in the developed world?”

Travis Rieder, a bioethicist at Johns Hopkins University, said he believed it was a good idea.

“I do think that we should at least consider it,” he told Nye.

“Well, ‘at least consider it’ is like ‘Do it,'” Nye said.

Rieder replied, “One of the things that we could do that’s kind of least policy-ish is we could encourage our culture and our norms to change, right?”

The comments not only sparked outrage on social media, but also a strong rebuke from Dr. Rachel Snow, chief of population development at the United Nations Population Fund, who was also on the panel.

“I would take issue with the idea that we do anything to incentivize fewer children or more children,” she said. “I think it’s all about … human rights. People should have the number of children they want … and if some families have five or six children, God bless them. That’s fine. But most people end up with fewer.”

Before Nye posed the controversial question, Rieder had claimed that children in developed countries such as the United States typically used 160 times more resources than those elsewhere.

The episode had been aimed at dealing with climate change — one of Nye’s most passionate subjects. The ’90s star has said in the past that he is open to throwing climate skeptics behind bars.

While some have praised Nye’s new show, it’s been blasted by many for being too provocative and biased. The series has received a dismal IMDb score of 4.4 out of 10.

“Bill Nye, you should reboot your old show so adult fans can introduce their kids to science…instead of taking a big s–t in their mouths,” a Twitter user wrote Tuesday.

“Wow! @BillNye the eugenics guy? He wants to punish people for having ‘extra kids.’ What’s an extra kid?” another tweeted.

One person added, “Bill Nye the Hitler Guy.”
