Add all of us up, all 7 billion human beings on earth, and clumped together we weigh roughly 750 billion pounds. That, says Harvard biologist E.O. Wilson, is more than 100 times the biomass of any large animal that's ever walked the Earth. And we're still multiplying.

Apples — right off the tree, baked in a pie, pressed into cider or mashed into sauce — are a basic element of American culture. October is the month to celebrate them, thanks, in part, to Johnny Appleseed.
You've probably heard of the legendary character who traveled the Midwest planting trees, but he's not a myth. Johnny Appleseed's real name was John Chapman, and he was born in Massachusetts in either 1774 or 1775.
