Last summer was harder than most for old trees and their human supporters. The spring’s nonstop rains flooded soils and caused root systems of many large, old trees to rot in part. Then, when the summer came, trees could not tap deep sources of water that would normally have maintained them. Many valuable old trees died. ? When I volunteered on the Mount Rainier Tree Commission, I heard from many people concerned about their trees. We had little to offer them. That’s because public and private urban tree resources and programs were aimed almost entirely at planting trees and not at all maintaining trees. No state or province program that I could find provided any financial resources for maintaining tree health. Small and under-resourced cities such as ours were on their own. This is backward. Scientists are learning that large, old trees are the most valuable, especially in cities. They put on wood fastest and take the most carbon out of the air. They harbor the most wildlife. They can lower summer temperatures by 20 degrees or more. In a recent study, researchers found that Boston would get more benefit from keeping the trees it has alive than from planting new trees. There’s the reason to think this finding would apply in other cities, too. Now, our public and private tree programs often ignore old trees until it is too late. As long as we abandon our old trees, planting more is merely to keep pace with growing losses. We want trees to help protect us, but we leave them unprotected. Consider this in the human world. Nobody would send a baby into the world and expect it to just make it. Children need caring for and it’s why we have schools and child health-insurance programs. We could get so much more out of our trees if we just put a little more into them. 【文章大意】本文是一篇夹叙夹议文, 通过对一些古树死去和大树能够提供人们的资源的描述, 来提倡我们要保护树木, 这样才能从树木身上获取更多的益处。 1.
