Use Tree-Free and continue to Breath Free. Everyone knows that trees are the lungs of the world. Yet, despite being in the middle of a digital revolution, paper still makes up ONE THIRD of all municipal waste (as of 2007). Making paper from trees is a horribly wasteful process, with only half of the tree being usable for paper pulp. Both the pulping process, and the bleaching process are toxic…and with world forests shrinking at an alarming rate, it is definitely time to take paper out of the forests and into the hemp fields.
