In April, Dorfman published The Lazy Environmentalist on a Budget, a sequel to his 2007 best seller “with the added filter of price -- solutions that are super stylish but more affordable.” Among his suggestions: Internet sites that promote reusing and recycling goods rather than buying new. These include the fashion exchange site Swapstyle.com, Neighborrow.com, where users lend and borrow goods, Paperbackswap.com, SwapaCD.com, and Goozex.com, a trading community for gamers. “It’s a way to get the things you want, but save money and consume less,” says Dorfman.
