“You cannot sustain population growth. It’s not debatable,” says University of Colorado Boulder Professor Emeritus Al Bartlett. “It’s based on arithmetic. It’s not debatable unless you want to debate arithmetic.”

Explaining the link between climate change and pine bark beetles

“On one hand, I’m gonna tell you, ‘This is no big deal, bark beetles have been around for 35 million years, conifers have been around for a lot longer than that, and bark beetles have been killing conifers for 35 million years. There have been epidemics every 30 to 70 years. This is no big deal.’

“Then, on the other hand, I’m gonna tell you, ‘Holy smokes guys, this has never been seen before. Yes, it’s an epidemic, yes, epidemics are natural, but never has there been an epidemic like this as far as biologists have been able to look into the past.”
