Katie Rosie Quant at the U.S. magazine Mother Jones gave some facts about plastic bags after California banned disposable ones in 2014:
• A bag is typically used for just 12 minutes.
• According to the Australian government, a car could drive 36 feet (3m) with the amount of petroleum used to make one plastic bag.
• For a paper bag to be better in terms of global warming impact, you have to use it three times.
• A cotton bag must be used 131 times before its global warming impact is less than single-use plastic bags.
• Australia cut usage of plastic bags by two-thirds through charging for them.
• Ireland imposed a tax on plastic bags in 2002 and cut usage by an estimated 75-90%.
In a New York Times op-ed, marine captain and researcher Charles J. Moore of California wrote: "We suspect that more animals are killed by vagrant plastic waste than by even climate change."
