A renowned University of California-Riverside professor recently advised students to save Mother Earth, eat vegetarian, only have 1.5 kids – two at the most – take up social justice causes, and “lower your standard of living.”

Biology Professor Richard Cardullo – recently tapped by several federal agencies to assist with redeveloping how college students across the nation study life science – offered the advice to a room full of middle school students as part of the university’s online science lecture series, recorded on the campus earlier this year. A video of his talk is posted on YouTube.

He began his 50-minute lecture, “Is Earth Overpopulated,” by painting a picture that the planet doesn’t have the room or resources for more and more humans, yet that’s the direction in which it’s headed. […]

Cardullo ultimately advocates family planning for the task.

“That means your generation and the next generation, if they are committed to doing this, would mean having family sizes that on the average are 1-and-a-half children, or two,” he said. “Some would have one, some would have two. It would be 50/50.”

Cardullo’s lecture then morphed into somewhat of a sexual education seminar, explaining to the students on a cellular level how sperm fertilizes an egg, and how scientists study new ways to stop that from happening.

“Sperm is a vector … which leads to increased populations, so many scientists want to know, ‘Are there new ways we can control population or fertility rates?’ … so individuals can make the decisions to keep those rates low,” he said. “We are talking about controlling human fertility.”
