I don't know if it's because the cities are too crowded, squeezing out all tender feelings, or it's that people think that without any trees they and future generations can still go on living well as long as they continue piling up material wealth.
不知是否因為都市太擠，把這種溫柔的心情擠壓光了，還是人們認為，沒有一點樹，他們和下一代還是都可以活的很好；只要財富得以累積。
