Just wondering why the article didn't reference Chinese artist Zhang Huan, who did some similar work in 94-95 or so, I think (To Raise the Level of Water 1 Meter, To Raise the Height of a Mountain 1 Meter) which I thought was more interesting. Not affiliated with him in any way, but saw the work in a touring show and was struck by it. Seemed to preach the humanity vs. the inhumanity.
