China
They call them 'chopsticks' for a reason - it's because they're from chopped-down trees. Vast tracts of forests are thoughtlessly used and thrown away every year.
Commendably, the PRC government is now beginning to crack down on this, and Japan for example has begun to tax imported chopsticks heavily. So to help this process along - anywhere in Asia for that matter - when dining in restaurants ask for (or bring along your own) plastic chopsticks. Wipe them with a tissue if you're worried about hygiene, it's not hard. And if you really can't handle the chopstick issue, bring a fork.
Yu Yuan Gardens (see www.ivebeenthere.co.uk/tips/1036) is a nice place to buy souvenir choppies - try the Shanghai Chopsticks Store, 31 Yuyuan Lao Lu
