ReThink Review: Plastic Planet -- Life in the Plastic Age

In the documentary Plastic Planet, director Werner Boote proclaims that just as the world experienced the Ice Age, the Stone Age and the Bronze Age, mankind is currently living in what could only be called the Plastic Age. First created in 1855 by Alexander Parkes, plastic is involved in every facet of modern existence to the point that life without it is unimaginable. Don't believe me? If you do a quick check, I'm willing to bet that you are currently touching at least three pieces of plastic right now. Looking around me, I could reach out and touch at least 50 plastic items (pens, tape dispenser, phone, printer, blank DVDs, etc.) and probably a lot more.

But plastic is not as benign as it appears. Plastic Planet attempts to tell the full story of plastic -- how it's made, where it goes, and how dangerous chemicals found in plastics make their way into the environment, the food chain, and eventually into the human body. Watch my ReThink Review of Plastic Planet and my discussion with Ana Kasparian of the Young Turks about how plastic chemicals enter your body, the effects they can have on the endocrine system, and some ways to keep plastic out of you.

In this video, I have one statistic wrong -- it turns out that it's 92.6 percent of Americans (not all humans) who have detectable amounts of plastic chemicals in their blood and urine, though BPA has been found in the air around the world. Unfortunately, that chemical is bisphenol A (BPA), a known endocrine disruptor that can mimic human hormones and has been linked to cancer, obesity, early puberty, diabetes and heart disease. You may remember a few years back when Nalgene was criticized for using BPA in their hard plastic water bottles favored by outdoorsy types (they've since stopped using it). The US and state governments have been restricting the use of BPA in products designed for babies and very young children, but BPA is still widely used in food packaging, including the linings of cans. To find out more about how countries are restricting BPA, go here.

Of course, the best way to keep plastic out of your body and the environment is to use less of it, especially when it comes to food. I recycled some old plastic containers and bought glass replacements for the two plastic items I use the most -- my juice pitcher and a large measuring cup I use to blend my smoothies. I already don't drink bottled water (nor should you for many reasons), and most of the food I buy doesn't come wrapped in plastic. I often store leftovers in plastic containers (including reused yogurt containers, which probably isn't a good idea), but will be looking into getting glass containers, possibly as a birthday gift (hint).
