National Geographic has a wonderful cover story this week on soil conservation. My favorite part is a photo (the last one in this gallery) that shows Kansas prairie grasses with roots that stretch a whopping 10 feet into the ground. It’s kind of that whole iceberg theory — much of nature is unseen on the surface.
PS: I’ve noticed that National Geographic has taken to referring to itself as “Nat Geo” on television … I mean, I’m all for abbreviations, but really? — J. Sut
