'Once Upon a Time's' Kristin Bauer Van Straten Signs on to Elephant Poaching Doc

'Earth Focus: Illicit Ivory' debuts May 27 on KCET.

Once Upon a Time's Kristin Bauer van Straten has signed on to introduce viewers to an upcoming KCET special examining elephant poaching and the illegal ivory trade.

Van Straten, who also co-starred on True Blood and is an elephant activist, will introduce the documentary Earth Focus: Illicit Ivory, which uncovers the devastating effects of the illegal ivory trade, its impact on the dwindling African elephant population and the link to insurgency groups and organized crime. It's set to premiere in L.A. on May 27 on Southern California's public TV station KCET and nationwide the next day at 9 p.m. PT/ET on the Link TV Network, available to Dish and DirecTV subscribers.

The special installment of Earth Focus, TV's longest-running environmental investigative series, is a partnership among KCETLink Media Group, the Wildlife Conservation Society and its 96 Elephants campaign, and the Los Angeles Zoo. According to their research, an elephant is killed by poachers every 20 minutes as part of a demand for ivory. African elephants may be gone in as little as 10 years as a result of organized crime syndicates, rebel groups, militias and insurgents.

The film also explores education initiatives letting consumers know that buying an ivory trinket means that an elephant actually has to die.

The documentary highlights other celebrities' elephant activism as well and includes Yao Ming, Edward Norton, Hillary Clinton and Prince William. Watch an exclusive clip above.
