Paper wrapper, friend or foe?

We know that recently people talk about the use of paper bag or paper wrapper. Related to global warming issue,people are suggested to use paper bag more, than using plastic bag. But is that really the best solution? Well we know that to produce paper we have to cut down many trees. Cut down trees means that we lost the vegetation in our forest,whereas we know that to decrease the global warming effect, we need trees and vegetation to provide more oxygen.
