In light of California banning plastic shopping bags I did some research and found that we in the US use 12,000 plastic bags a SECOND. Every second. Every day. 12,000 bags.
After we use as single bag to carry one peanutbutter jar and a bundle of celery from the trunk of the car to the house, we discard it, mostly into the trash, where they clog up landfills.
Another thought. Somebody makes that 12,000 bags a second. Those companies are probably suffering now, knowing that about 1/8 of their market is evaporating due to the California decision.
Oil is a major ingredient to making plastic bags.
