Like Ugg boots, red string bracelets, and hairless, yippy purse-dogs, charitable causes are subject to the ever-shifting, capricious cycle that affects all celebrity-assisted trends. Unfortunately for AIDS activists seeking famous faces to attract publicity to their work, the global pandemic suddenly finds itself last year's tired Cambodian adoptee to global warming's red-hot Namibian-born biological offspring. Reports the LAT:

At the moment, one of the hottest issues in town is the environment — and even AIDS activists agree that's a cause that is hard to argue with. "AIDS isn't going to matter if there's not a world left," said Bragman, who is also supporting the green movement.

Reflecting Hollywood's interest in the environment, Vanity Fair recently came out with a "green" issue featuring George Clooney, Julia Roberts, former Vice President Al Gore and Robert F. Kennedy Jr. on the cover.

It's not too late for the AIDS camp to push their cause back into the pages of the nation's glossy magazines and recapture the imagination of celebrities who have attached themselves to trendier problems. They can even co-opt the methods that have made global warming the most superficially discussed issue in Los Angeles' VIP lounges, where the Lohans and Hiltons of the world draw rough schematics for hybrid Bentleys on cocktail napkins while claiming that their mansions "seem, like, much hotter lately"—convincing Vanity Fair to publish a special AIDS issue with a cover featuring stalwart activist Elton John and his high-profile friends naked but for a series of strategically placed red ribbons would be a great way to jump-start a renaissance of interest among celebrities looking to have something important to say in between awkwardly silent moments on the red carpet with Ryan Seacrest.
