Paper, plastic, or reusable?

Katherine Mangu-Ward asks at Reason,

How did one of the most efficient, resource-saving inventions of the 20th century become an environmentalist bugaboo?

...About 65 percent of Americans report that they repurpose their grocery bags for garbage. By contrast, a survey by the marketing research firm Edelman Berland found that consumers reported forgetting their reusable bags on 40 percent of grocery trips and opted for plastic or paper instead.

...If you're like most people, here's what you have probably done at least once: Put a leaky package of chicken in your cloth or plastic tote. Then go home, empty the bag, crumple it up, and toss it in the trunk of your car to fester. A week later, you go shopping again and throw some veggies you're planning to eat raw into the same bag. Cue diarrhea.

...A 2011 survey published in the journal Food Protection Trends found coliform bacteria in fully half of the reusable shopping bags tested in a random survey of shoppers in Arizona and California. The same 2014 Edelman Berland study that found consumers frequently forgot their bags also unearthed the fact that only 18 percent of shoppers reported cleaning their bags "once a week or more." An article in the Journal of Infectious Diseases traced a 2010 outbreak of norovirus to nine members of an Oregon soccer team who had touched or eaten food stored in a contaminated reusable bag.

...Though it was meant as irony, there was an essential (if accidental) truth behind the speech. The technology behind plastic grocery bags is so useful it won a Nobel Prize. Employing an unimaginably small amount of base material, manufacturers can create tools of surprising strength and durability. Far from being the environmental threat activists make them out to be, plastic bags are not particularly to blame for clogged sewers, choked rivers, asphyxiated sea animals, or global warming. Instead, they are likely our best bet for carrying all of our junk in a responsible manner.
