Bring your own chopstick - a durational collection, 2001-2015
"Chopsticks add to a plague of regional deforestation. According to a 2008 United Nations report, 10,800 square miles of Asian forest are disappearing each year, a trend that must be arrested to fight climate change, given the vital role trees play in absorbing carbon dioxide. Activists argue that the disposable chopstick habit could gradually be phased out on an individual basis. Chopstick sets complete with a simple or decorative case are sold at many stores and are easy to put in a purse, knapsack or briefcase, they note." - New York Times
