A new prize for artists engaged with environment issues organised under the auspices of the French Ministry of Culture has been announced
The COAL Art & Environment prize was launched in 2010 by the French association COAL, the coalition for art and sustainable development, to reward a project about the environment by a contemporary artist.

Sustainability and Contemporary Art 
Recently I wrote a Marxist critique of the ideology of “Green” environmentalism, the locavore and organic food movements, deep ecology, permaculture, ecofeminism, “radical” environmentalism (Green anarchy, “veganarchism,” animal liberation, anarcho-primitivism) and lifestyle politics in general (veganism, “dumpster diving,” “buying organic,” “locavorism,” etc.). I’d be interested to hear your thoughts on the matter and any responses you might have to its criticisms.
