You have to be insanely dedicated to even consider removing plastic from the items you consume. Just too ubiquitous, in nearly every food packaging, on your clothing, on your shampoo, toothpaste, everywhere. The scientific proof of harm from the body may still be murky1 , but the fear of plastic is custom made for our worry-wart culture. Another thing to feel inadequate about being unable to change about our environment.
[Frederick vom Saal, a biologist at the University of Missouri] is a prominent member of a group of researchers who have raised worrisome questions in recent years about the safety of some common types of plastics. We think of plastic as essentially inert; after all, it takes hundreds of years for a plastic bottle to degrade in a landfill. But as plastic ages or is exposed to heat or stress, it can release trace amounts of some of its ingredients. Of particular concern these days are bisphenol-a (BPA), used to strengthen some plastics, and phthalates, used to soften others. Each ingredient is a part of hundreds of household items; BPA is in everything from baby bottles to can linings (to protect against E. coli and botulism), while phthalates are found in children’s toys as well as vinyl shower curtains. And those chemicals can get inside us through the food, water and bits of dust we consume or even by being absorbed through our skin. Indeed, the Centers for Disease Control and Prevention reported that 92% of Americans age 6 or older test positive for BPA–a sign of just how common the chemical is in our plastic universe.
Scientists like vom Saal argue that BPA and phthalates are different from other environmental toxins like lead and mercury in that these plastic ingredients are endocrine disrupters, which mimic hormones. Estrogen and other hormones in relatively tiny amounts can cause vast changes, so some researchers worry that BPA and phthalates could do the same, especially in young children. Animal studies on BPA found that low-dose exposure, particularly during pregnancy, may be associated with a variety of ills, including cancer and reproductive problems. Some human studies on phthalates linked exposure to declining sperm quality in adult males, while other work has found that early puberty in girls may be associated with the chemicals.
Does that mean even today’s minuscule exposure levels are too much? The science is still murky, and human studies are few and far from definitive. So while Canada and the Democratic Republic of Wal-Mart are moving to ban BPA in baby bottles, the Food and Drug Administration maintains that BPA products pose no danger, as does the European Union. Even so, scientists like Mel Suffet, a professor of environmental-health sciences at the University of California, Los Angeles, say avoiding certain kinds of plastics is simply being better safe than sorry.
As researchers continue to examine plastic’s impact on our bodies, there’s no doubt that cutting down on the material will help the environment. Plastic makes up nearly 12% of our trash, up from 1% in 1960. You can literally see the result 1,000 miles (1,600 km) west of San Francisco in the Great Pacific Garbage Patch, a swirling mass of plastic debris twice the size of Texas. The rising cost of petroleum may get plastic manufacturers to come up with incentives for recycling; current rates stand at less than 6% in the U.S. But the best way to reduce your plastic impact on the earth is simply to use less.

Don’t forget that the oil barons who run our country don’t really want to change anything that might interfere with profits, so don’t expect any FDA or EPA studies concerning the interaction with humans and plastics anytime before the Rapture.Footnotes:
