Shepard Fairey declared about that artwork :
"These “Factory Stacks” images combine the austere, angular power of factory architecture with graphic elements commenting on what we promote and embrace as a society even when those things are destructive. The fossil fuel industries have tremendous power economically, but we now know that not only are fossil fuel sources finite but that using them is terrible for climate change and, therefore, the eco-systems that sustain life on our planet. Unfortunately, due to the political power of these industries and public apathy about climate change, the government subsidizes the fossil fuel industries for billions even as they damage the environment. The government works for the citizens, so the choice is ours. Do we support endless power for wealthy fossil fuel corporations? Or policies that put the earth first with the planet before profits? Please read Naomi Klein’s THIS CHANGES EVERYTHING to better understand the conflict between economic interests and climate change. A portion of the original proceeds from the realease of this artwork went to Greenpeace to fight climate change. "
