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, towhom most of us rarely give a second thought, are so poorlyunderstood. We need to come, as soon as possible, to a profoundunderstanding and appreciation for trees and forests and the vitalrole they play, for they are among our best allies in the uncertainfuture that is unfolding.Jim Robbins

Even viewed conservatively, trees are worth far more than they cost toplant and maintain. The U.S. Forest Service's Center for Urban ForestResearch found a ten-degree difference between the cool of a shadedpark in Tucson and the open Sonoran desert. A tree planted in theright place, the center estimates, reduces the demand for airconditioning and can save 100 kilowatt hours in annual electrical use, about 2 to 8 percent of total use. Strategically planted trees canalso shelter homes from wind, and in cold weather they can reduceheating fuel costs by 10 to 12 percent. A million strategicallyplanted trees, the center figures, can save $10 million in energycosts. And trees increase property values, as much as 1 percent foreach mature tree. These savings are offset somewhat by the cost ofplanting and maintaining trees, but on balance, if we had to pay forthe services that trees provide, we couldn't afford them. Becausetrees offer their services in silence, and for free, we take them forgranted.Jim Robbins

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.Jim Robbins
