Fifty years ago today, the New Yorker began a three issue series entitled "Silent Spring" written by Rachel Carson. I don't think I need to introduce Rachel Carson or "Silent Spring" to anyone who reads this blog, but there's a very nice historical perspective on the history of "Silent Spring" at The Pop History Dig. If you're at all interested in Rachel Carson, you owe it to yourself to click through and read it.
