In the beginning of December of 2008, I listened to John D. Liu’s presentation of an ecosystem rehabilitation project in the Loess Plateau in China. At that event, only part of the documentary was shown because of time constraint.
I corresponded with John, who graciously offered me the link to the whole film, which is 52 minutes long. I watched it on Friday and, once again, really enjoyed it.
Here is the link to it. Highly recommended! Enjoy.
