While Amy Chavez's Dec. 29 column, "How can Japan help save the world? Be more Taiwanese," is an interesting piece, it did have one or two parts that I question. First, Chavez states that Taiwan's MRT subway uses plastic electronic tokens as well as modern smart cards that eliminate "unnecessary waste that would be generated with a paper ticket." Paper is also recyclable.

Next she states that "all of Taiwan's restaurants use reusable lightweight metal or plastic chopsticks — no more disposable chopsticks to burn or end up in landfills!" Plastic and metal have high carbon footprints; elements of both have to be dug out of the ground then processed. Wood is at least vaguely carbon neutral.
