Planting trees, I myself thought for a long time, was a feel-good thing, a nice but feeble response to our litany of modern-day environmental problems. In the last few years, though, as I have read many dozens of articles and books and interviewed scientists here and abroad, my thinking on the issue has changed. Planting trees may be the single most important ecotechnology that we have to put the broken pieces of our planet back together.

What an irony it is that these living beings whose shade we sit in,
whose fruit we eat, whose limbs we climb, whose roots we water, to
whom most of us rarely give a second thought, are so poorly
understood. We need to come, as soon as possible, to a profound
understanding and appreciation for trees and forests and the vital
role they play, for they are among our best allies in the uncertain
future that is unfolding.

Even viewed conservatively, trees are worth far more than they cost to
plant and maintain. The U.S. Forest Service's Center for Urban Forest
Research found a ten-degree difference between the cool of a shaded
park in Tucson and the open Sonoran desert. A tree planted in the
right place, the center estimates, reduces the demand for air
conditioning and can save 100 kilowatt hours in annual electrical use,
about 2 to 8 percent of total use. Strategically planted trees can
also shelter homes from wind, and in cold weather they can reduce
heating fuel costs by 10 to 12 percent. A million strategically
planted trees, the center figures, can save $10 million in energy
costs. And trees increase property values, as much as 1 percent for
each mature tree. These savings are offset somewhat by the cost of
planting and maintaining trees, but on balance, if we had to pay for
the services that trees provide, we couldn't afford them. Because
trees offer their services in silence, and for free, we take them for
granted.
