You mean they’re not doing this already?

(LA Times) — The United Nations has long courted celebrities for its peace-keeping and anti-poverty efforts, from Mia Farrow and Ricky Martin to George Clooney and Angelina Jolie.

It is a mutually beneficial arrangement. Hollywood stars grasp at gravitas; the U.N. pushes for publicity.

Now the beleaguered multi-national agency, fresh from a disappointing round of climate negotiations in Cancun, wants something more concrete: actual story lines in movies, television and social media drawing attention to the dangers of global warming.

The push comes at a time when public concern over climate change has plummeted in the polls and Congress has rejected federal legislation to curb greenhouse gas emissions.

“Usually I speak to prime ministers and presidents, but that has its limits” said U.N. Secretary-General Ban Ki-moon, who arrived in Los Angeles on Monday for a high-profile outreach effort. “Movie producers, directors, actors — they have global reach.”

Ban will sit down for a conversation with actor Don Cheadle before several hundred entertainment industry invitees at a “Global Creative Forum” Tuesday at the Hammer Museum.

The day-long gathering will feature panels titled “The United Nations and Hollywood for a Greener and Better Planet,” “Making Global Warming a HOT Issue” and “Empowering Women and Protecting Children for a Safer World.”
