use your library card.

Try borrowing books instead of buying them – it’s free! Americans buy about 1.9 billion books each year, which uses paper made from over 300,000 trees. Producing books is energy consuming, and usually means using petroleum-based ink. Try digging out your old library card and giving it a spin. Most county libraries in the US have made great strides technologically, and allow you to reserve and re-new books online, saving you the late fees, while saving precious trees at the same time.
