Shepard Fairey declared about that artwork :
"The title Black Earth Society is a play on the Flat Earth Society, an actual group of science deniers who think the Earth is flat… not dissimilar to the group of science deniers who think climate change is a hoax. The fossil fuel corporations have power from deep pockets. They use that power to sow the seeds of doubt about the danger of continued reliance on their products without a plan to transition to renewable energy sources. The power of laziness to keep fossil fuels as the status quo, the power of corporations to influence politicians, and the power of intentionally misleading the public are all forms of power we must fight against to keep our planet healthy. Proceeds from this print will benefit Greenpeace to assist their efforts to protect the environment and ween America off fossil fuels".
