(2021·嘉兴教学测试)One of the costs of being a lover of old trees is the alltoofrequent loss of a beautiful soul you've grown fond of .Last summer was harder than most for old trees and their human supporters.The spring's nonstop rain 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 (维持) them.Many valuable old trees died.
When I volunteered for 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 but not at maintaining trees.No state or province program that I could find provided any financial resources for maintaining tree health.Small and underresourced 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 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 healthinsurance programs.We could get so much more out of our trees if we just put a little more into them.
