Many store chains have taken initiative. In 2007,
introduced its "bag the plastic bag" program to the U.S., charging a nickel for plastic bags and offering an alternative reusable bag for 59 cents. In 2008, after a 92% reduction in use, Ikea stopped offering plastic bags altogether. Likewise, organic food behemoth
Whole Foods Market
banned plastic bags in 2008 and offers only paper bags made from 100% post-consumer content or a reusable bag for 99 cents.
Whatever one's opinion is on formal bans, it cannot be denied that plastic bags cause significant harm to wildlife and the environment.
Each year, between 500 billion to 1 trillion plastic bags are consumed worldwide, with billions winding up in landfills. We throw away almost 100 billion plastic bags in the U.S. every year.
Plastic bags can take up to 1,000 years to degrade, while plastic waste kills an estimated 100,000 marine creatures (including dolphins, sea turtles, seals and whales) and 1 million sea birds annually. These animals often are strangled or choke on the plastic when they ingest it, mistaking it for jellyfish or other food.
Plastic bags also can contribute to carbon emissions, since they are petroleum products that require intensive energy to make and transport. It is estimated that 12 million barrels of oil are needed to make 30 billion plastic bags.
Thrown-away plastic bags often wind up airborne and washing into waterways. The prevalence of plastic has led to two large islands of garbage in our oceans, known as the Great Pacific and the North Atlantic garbage patch, respectively. The Great Pacific garbage patch is twice the size of Texas; the North Atlantic garbage patch has at times waxed to a maximum length of 990 miles.
It is estimated that we successfully recover and recycle only 1% to 3% of the plastic bags we use in the U.S. In those cases where plastic bags are "recycled," they are often done so improperly by people tossing them carelessly in with recyclables on trash pickup days, where they go on to jam and damage expensive sorting machines.
Studies show that people often do not take the initiative to return plastic bags to stores for recycling even when the option is available, and even when plastic bags are returned to stores for recycling they are actually downcycled -- that is, converted to a product of much lower quality than its original form.
So what's a good alternative?
In addition to refusing plastic shopping bags for single items that can easily be carried by hand, consumers should buy and make use of reusable cloth shopping bags. Canvas bags are 14 times better than plastic bags and 39 times better than paper bags from an energy standpoint, and can be used up to 500 times during their life cycle, according to a study by Australia's government.
