“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.”

“The planting of a tree, especially one of the long-living hardwood trees, is a gift which you can make to posterity at almost no cost and with almost no trouble, and if the tree takes root it will far outlive the visible effect of any of your other actions, good or evil.”

“A person should be buried only half a meter, or two feet, below the surface. Then a tree should be planted there. He should be buried in a coffin that decays so that when you plant a tree on top the tree will take something out of his substance and change it into tree-substance. When you visit the grave you don’t visit a dead man, you visit a living being who was just transformed into a tree. You say, “This is my grandfather, the tree is growing well, fantastic.” You can develop a beautiful forest that will be more beautiful than a normal forest because the trees will have their roots in graves. It will be a park, a place for pleasure, a place to live, even a place to hunt.”

“Concerning trees and leaves... there's a real power here. It is amazing that trees can turn gravel and bitter salts into these soft-lipped lobes, as if I were to bite down on a granite slab and start to swell, bud and flower. Every year a given tree creates absolutely from scratch ninety-nine percent of its living parts. Water lifting up tree trunks can climb one hundred and fifty feet an hour; in full summer a tree can, and does, heave a ton of water every day. A big elm in a single season might make as many as six million leaves, wholly intricate, without budging an inch; I couldn't make one. A tree stands there, accumulating deadwood, mute and rigid as an obelisk, but secretly it seethes, it splits, sucks and stretches; it heaves up tons and hurls them out in a green, fringed fling. No person taps this free power; the dynamo in the tulip tree pumps out even more tulip tree, and it runs on rain and air.”

“In a designed economy there would be no trees, or certainly no very tall trees: no forests, no canopy. Trees are a waste. Trees are extravagant. Tree trunks are standing monuments to futile competition - futile if we think in terms of a planed economy. But the natural economy is not planned. Individual plants compete with other plants, of the same and other species, and the result is that they grow taller and taller, far taller than any planner would recommend.”

“It's Earth day I wonder if we can plant more trees than people for a change?”
