Sustainable Swells

The rich and famous don't have to give up their caviar dreams to go green. Roe from U.S.-farmed sturgeon and trout (below) are gaining cachet as an environmentally friendly alternative to overfished  beluga sturgeon. And where better to enjoy these delicacies than in a luxe living room at the Solaire, one of the energy-efficient, green-roofed highrises popping up in Lower Manhattan? As night falls, the eco-elite might don a couture coat made of recycled soda bottles and hop into an eye-catching all-electric car--perhaps a speedy Tango like the one actor George Clooney drives to the set (above). That's the beautiful people for you--always doing their part.
