When it comes to speaking on the topic of climate change, Scottish Parliament believes Leonardo DiCaprio is the most qualified candidate. Leonardo has been an outspoken advocate on the subject since releasing The 11th Hour, his documentary outlining issues such as global warming, deforestation and animal extinction.

Patrick Harvie, a member of the country's Green Party, wrote a letter asking Leonardo to speak in conjunction with a Climate Change Bill, which was recently introduced to the government. Harvie's letter stated, "It would be a great help were you able to speak to other members of the Parliament about the urgency of the threat we face." The proposed bill strives to reduce carbon dioxide emissions over a long-term period. The Green Party has not yet heard whether DiCaprio will accept or decline the invitation.

Patrick Harvie is at the very least, demonstrating his keen PR instincts. Inform mass media you've asked Leonardo DiCaprio to speak on your behalf, but haven't heard back. Now Leo will look like the world's biggest jackass (and lukewarm activist) if he declines, even if it's for a legitimate reason.

You can watch the trailer for The 11th Hour below. After all, it's apparently made DiCaprio the reigning expert (next to Al Gore) on the issue. As for me, Leo's narration in the documentary is far too distracting, and I can't help but watch the trailer and half expect him to scream "I'm the king of the world!" mid-sentence.
