Pervasive Plastics: Why the U.S.
Needs New and Tighter Controls
Long a ubiquitous part of modern life, plastics are now in everything from diapers to water bottles to cell phones. But given the proven health threats of some plastics — as well as the enormous environmental costs — the time has come for the U.S. to pass a comprehensive plastics control law.

Since 1950, plastics have quickly and quietly entered the lives and bodies of most people and ecosystems on the planet. In the United States alone, more than 100 billion pounds of resins are formed each year into food and beverage packaging, electronics, building products, furnishings, vehicles, toys, and medical devices. In 2007, the average American purchased more than 220 pounds of plastic, creating nearly $400 billion in sales.
It is now impossible to avoid exposure to plastics. They surround and pervade our homes, bodies, foods, and water supplies, from the plastic diapers and polyester pajamas worn by our children to the cars we drive and the frying pans in which we cook our food.
The ubiquitous nature of plastics is a significant factor in an unexpected side effect of 20th century prosperity — a change in the chemistry of the human body. Today, most individuals carry in their bodies a mixture of metals, pesticides, solvents, fire retardants, waterproofing agents, and by-products of fuel combustion, according to studies of human tissues conducted across the U.S. by the Centers for Disease Control and Prevention. Children often carry higher concentrations than adults, with the amounts also varying according to gender and ethnicity. Many of these substances are recognized by the governments of the United States and the European Union to be carcinogens, neurotoxins, reproductive and developmental toxins, or endocrine disruptors that mimic or block human hormones.
