"Laurie David: 'When I talk about toilet paper and paper towels, which are made of virgin wood, people gasp,' David said. 'I tell them, when a 100-year-old tree is cut down ... so that we can have disposable paper products, is this acceptable? Should we still be using virgin trees for this?' The green solution: 'If every American household changed just one roll of paper made with virgin wood to one recyclable post-consumer roll, half a million trees would still be standing.' She's made the switch to post-consumer paper -- products made of paper previously used by consumers, then recycled -- in her own home despite initial complaints about the toilet tissue's not-so-squeezable texture from her husband, Larry David, creator of 'Seinfeld,' and his own HBO comedy series, 'Curb Your Enthusiasm.' 'My family is adapting,' said David, noting that her kids recycle and take shorter showers. 'Besides, they are making softer toilet paper now so I think we're O.K.'"
