CHICAGO—  In North America, we grow many more trees than we harvest  there are  20% more trees in North America today than there were on the first Earth Day in 1970.Paper manufacturers encourage forest sustainability through  promoting sustainable forest management policies. By providing a dependable market for responsibly grown fiber, the paper industry encourages landowners to manage their forestland instead of selling it for development or other non-forest uses. Each year forests in the U.S. and Canada grow significantly more wood than is harvested. In the U.S., average net annual increase in growing-stock trees nationwide is about 26 billion ft³.6 In 2015, Canada harvested just over 5.6 billion ft3 of timber, well below the estimated sustainable wood supply level of 7.98 billion ft³. Claims like “go paperless – save trees” create a false impression that forests are a finite resource, being destroyed. In truth, North American forests are a renewable resource that is continuously replenished using sustainable forest management.8
