From reuseit.com, here are some  Fast Facts on Plastic Bags:

Market Tote from GraniteGear.com

• 500 billion to 1 trillion plastic bags are used every year, worldwide.
• About 1 million plastic bags are used every minute.
• A single plastic bag can take up to 1,000 years to degrade.
• More than 3.5 million tons of plastic bags, sacks and wraps were discarded in 2008.
• Only 1 in 200 plastic bags in the UK are recycled (BBC).
• The U.S. goes through 100 billion single-use plastic bags. This costs retailers about $4 billion a year.
• Plastic bags are the second-most common type of ocean refuse, after cigarette butts (2008)
• Plastic bags remain toxic even after they break down.
• Every square mile of ocean has about 46,000 pieces of plastic floating in it.

We’re talking about, we suspect, two main uses: bags used in the transportation of goods – and bags used to transport “waste,” including the garbage bags themselves, discarded shopping bags – and sometimes shopping bags re-used as garbage bags.

Tara Lohan, in The Great Plastic Bag Plague,  (On Alternet, 2007), cites industry sources for the proposition that American retailers spend $4 billion/year on plastic bags – adding, of course, to the cost of goods – without reflecting their full environmental cost. Lohan cites other sources for the proposition that 12 million barrels of oil are used , annually, to produce plastic bags used in the United States. The U.S. Energy Information Administration estimates that average daily use of petroleum products in the United States – the world’s largest consumer – is 18,771,000 barrels/day. Assuming we’re not in a leap year – 1/365th is .0027 (rounded) of our energy consumption. Put another way, slightly over one-quarter of one percent (0.27%). And 12 million barrels would be about two-thirds of that.  Thought of another way – 18 million barrels per day – 365 days per year – 6.5 billion (6,570,000,000).  So plastic bags amount to 0.18% of our petroleum consumption.  1 component of  6,570 equal components. So what difference does it make if you accept a plastic bag, or bring your own reusable bag?

In WW II ((One of the ways in which the  Allies gradually wore down the Axis was by depriving it of – no surprise, we hope – petroleum.  Richard Overy, in Why The Allies Won, contends that Allies’ gradual degradation of Axis energy supplies made a great contribution to the eventual Allied Victory.))     , three million soldiers retook the continent (the invasion of Western Europe, sometimes referred to as Operation Overlord)  during and after D-Day. Each soldier’s contribution amounted to 0.12%  One in three million – without counting the various Resistance groups, support troops and civilians in the United Kingdom and the United States.  Total U.S. troop count: 16.5 million. The Philippines suffered over 50,000 military deaths alone. (For total WW II casualties, see Wikipedia entry of that name).

So  – the aggregate of many small, coordinated contributions is dramatic. Get a reusable shopping bag, and use it. In future posts, we hope to point out some good deals on reusable bags, and revisit the principle of aggregating small acts.
