Reevaluating Aldo Leopold's land ethic is timely, but Boris Zeide's cr
itique of it is both biased and logically flawed. The real target of Z
eide's essay is ecosystem management. The real sciences in which the l
and ethnic is grounded are evolutionary biology, community ecology, an
d ecosystem ecology, not the outmoded Clementsian superorganism paradi
gm in ecology. Although Zeide believes in a strictly zero-sum world, A
ldo Leopold had faith that we could achieve win-win solutions: log our
forests and maintain their health and integrity; prosper economically
and protect our ecological heritage.
