It’s hard to keep up with Belgian street artist ROA (previously here and here), who has been bringing his spray-painted monochromatic depictions of animals to all corners of the globe. This year he’s been to Portugal, Austria, Canada and the U.K. (just to name a few), and then to the U.S.

“I wanted to draw attention to how they and many other species become a victim of hunting and pollution,” says ROA, referring to a piece he did in Sweden of a narwhal caught in a fishing line. Indeed, ROA’s works are often accompanied by an environmental narrative that highlights the ruthless, man-made world animals are forced to live in. You can see much more of ROA’s work over on Brooklyn Street Art.
