The man who made it big as "Bill Nye The Science Guy" used a string of F-bombs to emphasize his thoughts on climate change and rising ocean temperatures. The former children's show host was trying to make a point about the cost of going green. It was part of a segment on HBO's Last Week Tonight with John Oliver. The NSFW comments start after he lights a globe on fire. That's when he points to a fire blanket, fire extinguisher and bucket of sand saying "none of this is free".

“I didn’t mind explaining photosynthesis to you when you were 12. But you’re adults now, and this is an actual crisis, got it? Safety glasses off, motherf*****s.”

The internet was quick to pounce on the comment with both supporters and critics weighing in on the rant. Watch the NSFW clip below:
