...know where to find a good plastic-free shampoo, can you tell Jeanne Haegele? Last September, the 28-year-old Chicago resident resolved to cut plastics out of her life. The marketing coordinator was concerned about what the chemicals leaching out of some common types of plastic might be doing to her body. She was also worried about the damage all the plastic refuse was doing to the environment. So she hopped on her bike and rode to the nearest grocery store to see what she could find that didn't include plastic. "I went in and barely bought anything...
...right. Back when Dustin Hoffman received the most famous one-word piece of career advice in cinema history, plastic was well on its way to becoming a staple of American life. The U.S. produced 28 million tons of plastic waste in 2005--27 million tons of which ended up in landfills. Our food and water come wrapped in plastic. It's used in our phones and our computers, the cars we drive and the planes we ride in. But the infinitely adaptable substance has its dark side. Environmentalists fret about the petroleum needed to make it. Parents worry about...
...Saal 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...
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...
What Wright actually envisions is not a Great Wall of proprietary plastic, but fields of much smaller, mass-produced scrubbers, each fitting into a 40-ft.-long (12 m) shipping container. Scatter 20 million of them in remote spots around the world, and you could take care of the emissions from all the vehicles on the planet. And what do you do with the carbon you collect? For starters, you could sell captured greenhouse gasses to, well, greenhouses; farmers pay up to $300 per ton for the stuff to help plants grow. If the scrubbers were deployed on a grand...
