Via a reader tip, Fox 5 reports that Greenpeace has taken responsibility for the polar bears that have been mistaken for suspicious packages around town over the last week. Indeed, if you go to the Greenpeace homepage, it turns out that not only was Greenpeace responsible, but they actually did it in collaboration with street artist Mark Jenkins — so both of our guesses were correct!

Greenpeace has unveiled a collaborative art project with well-known street artist Mark Jenkins. The project highlights the shared plight of polar bears and humans in the face of global warming. We hope these polar bear street art installations help people draw a deeper and more immediate connection to the reality of the crisis.

Jenkins, a Washington, D.C.-based artist who creates sculptures primarily from packing tape, has earned international recognition for his street art installations, many of which feature astoundingly realistic human figures. For this series, Greenpeace and Jenkins added polar bear heads and ragged clothing to human figures to convey a sense of displacement and homelessness. To date, four sculptures have been deployed throughout the D.C. area in locations chosen to reach a variety of audiences and address different aspects of the global warming crisis. One bear bore a sign reading “S.O.S.,” while another had signs saying: “Victim of Oil Addiction” and “Global Warming Refugee. Help a brother out?”

“My intention with this project was to leverage my street installations to promote awareness about the issue of global warming and the plight of the polar bear,” said Jenkins. “It was our shared goal that the public would develop empathy for the polar bear as they have for the homeless which we see as two connected issues.”

Given how much media attention the fake bear bomb scare got yesterday, we can safely say this tactic was a big success for Greenpeace. It’s also not the first time they’ve sent a polar bear to Washington.
