Green Environment    What’s the human-environment relationship? How did the older generation see the Earth 50 years ago? How will our next generation see the Earth in 50 years time? Because the older generation couldn’t truly understand the relationship between humans and the environment, we have to take many problems they left. In that case, will our descendants challenge us as well: “why couldn’t you understand: money is not everything until the lasttree is felled and there are no fish in the sea?”
