Jimmy: I really love Leonardo DiCaprio. In addition to being a great performing artist, he is sincere in his effort to champion the world environmental cause. And not only is he an excellent spokesman, he also walks the walk even to the point of flying commercial rather than by private jets. He ranks with Ed Begley Jr. and others who live by example, and that says something to me.

Other people don't get me as excited. Now I understand that artists, entertainers and world environmental leaders have different security needs and are often bound by this, but where does the line cross between a machiavellian end justifies the means soot-belching locomotive to environmental Shangri La compared to life by example? What is sincerity and what is sophistry? And does all of this help or undermine the cause? That's the topic of our discussion.

The auction is for a lunch date with conservationist and legendary actor Harrison Ford. Here's my deal — I think it is wonderful that celebrities are the models, the gift and the prize… I just hope we aren't auctioning off Brad Pitt's body parts for solar panels. Too far? — perhaps. Unrealistic? — perhaps not.

In other news, Leonardo DiCaprio visited Israel for the first time this past week with Israeli model girlfiend Bar Refaeli. (Is she hotter than ex Giselle — I don't think so) Sure there were walks on the beach, romance and violence with the paparazzi – but Leo had enough time to squeeze in talks with the Israeli government. The star was invited to meet with Israeli Vice Premier and former Prime Minister Shimon Peres within hours of arriving in Tel Aviv.

From the article:

An aide to Peres said: "The meeting was pleasant and interesting. Shimon told Leo about his Peace Valley project - a joint Israeli-Jordanian-Palestinian economic development plan - and Leo spoke about '11th Hour' his documentary on the environment."

Just another day in the life of Leonardo DiCaprio.

J.K. Rowling is not only making hard core green cash, she’s contributing to the green movement. I can hardly wait for the final book, Harry Potter and the Deathly Hallows, coming out July 21st. I can feel a little bit better about the monstrous 784 pages because of the alliance she’s made with Rainforest Alliance,

Among the details of agreement:

• The paper used will contain "a minimum of 30 percent post-consumer waste (pcw) fiber."
• Nearly two-thirds of the 16,700 tons of paper will be approved by the Forest Stewardship Council, an international organization with a mission to "promote environmentally responsible, socially beneficial and economically viable management of the world's forests."
• A "deluxe" edition of the new book, which has a first printing of 100,000, will be printed on paper that contains "100 percent post-consumer waste fiber."

Also, Julia Roberts is stepping into the limelight with plans to upgrade her 20 million dollar Malibu home with state-of-the-art green gadgets and technology. She also plans to add recycled tile to her bathroom floor. I'm all for these improvements. While everyone can do their part, regardless of financial state, it's cool to see what 'no budget' can do to produce a stylish and eco-friendly home.

Global Green USA, the environmental organization fighting the challenges of climate change, weapons of mass destruction and providing clean water for the millions without, also knows how to party. I know what you’re thinking: this is just another ploy for celebrities to celebrate themselves. Not so, counters Global Green USA president-CEO Matt Petersen, "A party cannot stop global warming, but it can be a great tool." And a lot of fun as well!

Global Green hosted the Pre-Oscar Bash, February 21^st at the Avalon Club in Los Angeles to promote more environmentally friendly lifestyles. Many celebs, including Penelope Cruz, Orlando Bloom, James Blunt and his supermodel girlfriend, Petra Nemcova walked down the green carpet. According to USA Today, flirtation between Blunt and Nemcova reached a green level when asked who was more eco-savvy. Blunt demurred, "I think we have an equal interest"; Nemcova just giggled and countered, "Competition is good." Finally, the environment has sex appeal!

Orlando Bloom was also on the scene, showing up in his a plug-in hybrid car and buzzing on his new eco-friendly home in London. “It's as green as I can make it. It's got solar panels on the roof, energy efficient light bulbs - newer technology basically that is environmentally friendly.” Judging by Orlando’s hair at the event it also appears he may be placing his fingers in energy efficient light sockets.

Orlando has been joining the pack of green celebs, led by Leonardo DiCaprio a huge promoter of Global Green and Brad Pitt (who recently received a beautiful EcoGreen Fireplace). A lot of celebs are stepping forward to make a difference, or at least putting their name on the list for the new Tesla Roaster.

This all-electric sportscar has already been ordered by over 330 celebrities, including George Clooney. According to Tesla vice president Darryl Siry, it’s ‘faster than most Porsches’ from 0-60. Fortunately, it looks better too.
