"The trick is to include nature as a fundamental part of
cities – not a tacked on afterthought. What most urban ecologists call for is a
larger rethink of cities as natural ecosystems with their own metabolism – a
blend of natural space, wildlife and built structures, not unlike a river with
a beaver dam. Instead of adding green to urban blueprints, they argue for the
“biophilic city,” an urban space that is natural in its own right, with green
included from the ground up. Features such as living walls, in which greenery
is planted vertically, or cookie-cutter parks may amount to little more than
green-washing, argues Joseph Juhasz, a professor emeritus in the architecture
faculty at the University of Colorado at Denver. “They dress up the city, grow
cucumbers on the wall, but they don’t deal with the fundamental problem – we
have to build in a manner in which the site does not dictate the building.” Like
many environmentalists, Dr. Juhasz says urban planners too often settle for
short-term design that leaves a long-term footprint. “We have lost a sense of
custodianship. Will their great-grandchildren be happy with what they have
built?”"--Erin Andersson, www.theglobeandmail.com
