And is it also true that it takes 2-3 tree to make one pad of paper?
In terms of tree-->paper, no, read
linkHowever, do consider the amount of energy needed to transport the trees, liquify the trees, set the goo (or however they do it now), cut the finished product, print lines, glue it together, transport to your local office supply store; it does amount to, maybe, a few trees being burnt to produced the finished product from a tree in a field. That being said, I've little comprehension of how much it actually takes to make a sheet of paper, let alone a pad but the energy use to move stuff around to make paper is decently large and may be the equivalent of burning several trees.
