Statistical Grok: Trash Talk Or a Look at Plastic Waste

“Just one word. … Plastics.” This classic line predicting the rise of an industry from director Mike Nichols’s The Graduate was prescient. Consider the increased use of plastic since the film’s 1967 release. From DVDs and prepackaged foods to that iced coffee to-go (right down to the straw) and the ubiquitous water bottle toted by so many Americans, plastic is pervasive and it’s wreaking havoc on our environment. You know what happens to the stuff when we’re done with it?

Some makes it into landfills. Lots float out into the ocean where marine life mistake it for food and suffer dire consequences. And a lot washes up on shore, polluting our beaches. Plastic stays with us longer than we think. Because it can’t biodegrade, it just breaks down into smaller and smaller pieces that last hundreds of years. A quick look at the numbers suggests cutting back on plastics could go a long way toward cleaning up our coasts without even having to step foot on a beach.
