14. Just a teaser

The article in the link is very cool and informative, as you note, passiveporcupine.

Pardon my tiny pin-prick: Bill McKibben is an American environmentalist, author and journalist and I believe his writings have been published in The New York Times, The Antlantic and many other publications.

Of course, you were referring to the interview with Professor Bill McKinnon in the linked article.

By explanation of my observation, my last name is McKibbins and this is always an issue!
