I’m an environmentalist. Love trees and forest. I teach people to be a sustainable citizen in Xidian university at Xi’an. Travel around to visit magnificent ancient trees. My passion is the preservation of the forest and the cultural landscape in global forest, and also the possible combination between environmental science and environmental ethics. To tell you the truth, I am actually confused by the issue of naturalistic fallacy, the dichotomy between the facts and the value. Aha, guess you might help me to solve the conundrum!
