The US currently uses 20 million barrels of oil per day. First we’re going to ban plastic bags, slicing away a giant 0.16% of that consumption. Now, bring on the plastic bottle ban, slashing a full 0.02% from the oil guzzling. Take that, global warming!We have a reusable bag from Tescos. It's environmentally friendly and I get points when I use it and don't use a plastic bag. Some of these things are even fashion statements. The other week I emptied it out and was astounded by all the packaging that the food I had bought was wrapped in. There are at least enough there to make 10 plastic bags. Suddenly it all seemed rather pointless.
