If a man walks in the woods for love of them half of each day, he is in danger of being regarded as a loafer. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen. – Henry David Thoreau

Trees outstrip most people in the extent and depth of their work for the public good. – Sara Ebenreck, American Forests
