None. Zero. Nada. Not a single tree is cut down to make the great American greenback. It’s not because the government has instituted an environmentally responsible recycling program, but rather because the paper used for currency is completely unlike the stuff we use for printing and writing. Wood pulp-based paper is designed to be affordable and mass produced, but is not necessarily very durable. Paper money, on the other hand, needs to be able to survive years of wallets, pockets and vending machines. It also needs to be difficult to reproduce, as a way of deterring forgery. So those bills in your pocket are actually more like fabric, made from a unique, legally-protected blend of cotton and linen fiber.
