some rough idea continued ...

keep reading 《Mapping the Terrain》 ... ...

In fact, quite a few cases in the book are good examples with environmental concerns, and the impact last till today.

Such as Joseph Beuys' 7,000 Oaks (七千棵橡樹, 1982-87) , Mel Chin's Revival Field (田野再生, 1989~), Betsy Damon's Keepers of the Waters (蓄水的人, 1991-93) and L.A. River Project, (洛杉磯大河計劃, 1989-92), and, of course, not to mention Helen Mayer Harrison and Newton Harrison.

Coincidently, the Barbican art gallery in UK is going to open a big exhibition on the same footing:

Radical Nature
Art and Architecture for a Changing Planet 1969–2009
19 June 2009 - 18 October 2009


Eco- and Public art seem to share some common ground.

Worth to have a look while there.
