Decked with tinsel and ornaments, evergreens鈥攆armed or fake鈥攄efine holiday cheer. Experts say that the best choice is going natural. From a climate-change perspective, you鈥檇 have to keep your artificial tree for 20 years before it became a better alternative than the real deal.

鈥淚f you like live trees and want to build a tradition, they鈥檙e a great choice and not environmentally harmful,鈥 says Clint Springer, a biologist at St. Joseph鈥檚 University and a tree expert.

Americans will buy about 21.6 million real trees and 12.9 million artificial ones this holiday season, reports Nielsen Research in partnership with the American Christmas Tree Association, an artificial tree group. (Numbers from the natural tree group, the National Christmas Tree Association, show that consumers bought 28 million natural trees and 8.2 million artificial ones in 2010.)

Most of the artificial variety come from China, so shipping them burns fossil fuels, says Jean-S茅bastien Trudel, founder of the Montreal-based consulting firm Ellipsos, which conducted a lifecycle analysis of natural and artificial trees. They鈥檙e also made from polyvinyl chloride, which emits volatile organic compounds that can lead to respiratory irritations and distress.
