Endangered Species Take Over Empire State Building Favorite 

In July 2015, the Empire State Building's famous light displays were used to draw attention endangered wildlife. Along with Cecil, whose death has sparked international outrage, a snow leopard, tigers, lemurs, and various snakes, birds and sea creatures were projected onto the building.

The spectacle was staged to promote the documentary "Racing Extinction," a production of the Oceanic Preservation Society. Cecil wasn't included in the presentation originally but was added to honor him after he was killed, an Oceanic Preservation Society spokesperson said.

With the help of 40 projectors, images of the endangered wildlife moved across the south side of the building, dazzling viewers on the street and in nearby buildings. The moving images were a first for the Empire State Building, which is normally lit with colors and the occasional light show.

The production was the collaborative effort of the Oceanic Preservation Society and the filmmakers of Racing Extinction, an upcoming documentary film that highlights humanity's role in the loss of the world's endangered species. Helmed by Louie Psihoyos — the director of The Cove — Racing Extinction follows a team of activists on a mission to expose the two largest threats to biodiversity — the international wildlife trade and society's growing carbon footprint. Rising carbon emissions have led to the acidification of Earth's oceans, causing the widespread deaths of many shelled sea creatures. And effects from climate change have led to the habitat loss of threatened species across the globe.
