Not long ago, I criticized one of my classmates of printing papers on one side only. After reading an article from Harvard economics professor Ed Glaeser, I have second thoughts on that. Here is the excerpt:
Our paper recycling programs cost time and money and do little to protect first-growth woodlands and rain forests. The trees used by paper mills are a renewable resource. When people use more paper, suppliers plant more trees. If we want bigger commercial forests, then we should use more paper not less. Our policies should directly protect important wildlife habitats, not try to reduce our demand for paper.
I totally get his idea. Limiting the demand is not going to help plant more trees. Stimulating the supply will just do that. But I'll still print the papers double-sided, only for the reason that I can carry less in my backpack.
