Astrophysicist and Cosmos host Neil deGrasse Tyson blasted critics of genetically modified foods — often referred to as GMOs — in a video recently posted online, saying they are part of a longstanding process of humans altering the planet’s biology to serve our needs, Mother Jones reported.

“I’m amazed how much rejection genetically modified foods are receiving from the public,” deGrasse Tyson tells a French interviewer. “It smacks of the fear factor that exists at every new emergent science, where people don’t fully understand it or don’t fully know or embrace its consequences, and so therefore reject it.”

What most people do not know, Tyson argued, was that almost any food bought in stores today has been modified before making it to the shelves.
