Where is the morality there?
It's Taoist morality. Taoism believes in allowing one's self to flow with the Tao like a log flows with a river(damn they like their water analogies). The water is moral in the Taoist sense because it does not try to destroy the mountain, or slash the earth. It just does. Action through inaction, wu-wei, pu, and such.

As to environmentalism. Destroying the environment ranks pretty high up on the dumb scale. If you destroy the environment you destroy yourself because we rely on the environment to provide food, water, oxygen (mildly important), and general enjoyment. Destroying it is like a runner cutting his leg off.
