I have several favorite DoomSlayers. Chief among them is Julian Simon. New DoomSlayers on the horizon are Bjorn Lomborg and Matt Ridley. Mr. Ridley is becoming more widely known because of his new book, The Rational Optimist. He is also being attacked by people who are of the Doom & Gloom crowd.
A great new piece by Mr. Ridley has caused me to do something I never thought I would do... provide a link to the Huffington Post. Regardless of where this article is posted, it is worth a read by anyone.
