It is true that most plastics are still made of petrochemicals, but more and more plastics are being made of corn, beans, and other biomasses as polymer technology advances. I feel that you will see less plastics made from crude oil byproducts as refining techniques and get better and oil supplies start to dwindle. Already there are at least two companies mining landfills for waste plastic, cooking it down, and making a higher quality gasoline than can be had at the pump. With that said, I would worry more about the rising cost of grains and related crops than pocket pages or 2x2's.
