Once a society pits itself against nature, people alter. Many of us live in an environment in which it is virtually impossible to see a single green tree or an expanse of green grass. Yet greenery is extremely important to man, for mankind was originally nurtured by the soil.
社會一旦反自然，人性就變了，我們的生活環境快要看不到一棵綠樹、看不到廣闊的綠地了，而綠對人很重要，人類是由綠地孕育出來的。
