How effective is saving paper?

Yesterday i was discussing with my friends, I got numerous suggestions about saving paper by re-using papers printed on one-side for "personal" print-outs.

Though I don't oppose these ideas, I have my reservations about their efficacy. Following are the questions that have surfaced to my mind repeatedly.

- Trees cut for making papers have to be replanted because, we will run out of papers otherwise. We have no idea about the number of trees we are losing because of making papers. We also don't seem to be running out of papers. So, in the end we don't know if we are really causing a significant depletion of trees. May be we are, but is there data?

- The only way to cut lesser trees without compromising the supply of paper is to recycle paper. India seems to have a defunct system of recycling wastes. If we are indeed degrading environment by cutting a lot of trees, it is possible that this trend can be more significantly minimized by putting a system in place that recycles most of the paper wastes when compared to small initiatives in individual companies to save papers.

Of course we are better off taking these small initiatives irrespective of the status of recycling, but my concern is, we have no way to measure how many trees we end up saving. What if the contribution of 100 companies with an average of 100 employees actually comes to saving 5% of trees, while setting up a recycling plant that can recycle paper in the neighborhood (companies, homes, schools any and building where paper is used) can reduce the number of trees cut of paper by 50%?

Simply put, how can one make this initiative measurable? Is there a comprehensive and accepted research that can answer my questions?

I am just thinking aloud. I may have been a bit hazy in putting my points with correct information. Experts comments are invited
