Just a moment!
Thanks to Ed Marston for critiquing both Gregg Easterbrook's A Moment on the Earth (HCN, 5/29/95) and the gaffes of environmentalists.
A friend from Philadelphia tells me that the leaf pictured on the book's cover is a Norway maple - a weedy tree species currently wreaking havoc in Eastern woodlands. An image picked to symbolize regeneration actually epitomizes one of the major causes of declining ecosystems: that of introduced plants crowding out the habitat-providing natives. Apparently Easterbrook truly can't tell the forest from the trees.
