How we became corrupted by plastic

In 1957, 92 percent of American children were potty-trained by 18 months of age. Four decades later, that number had dropped to just 4 percent. Why are we potty-training our children so much later than our grandparents did? In large part because of disposable diapers. Made from plastic and cellulose, these products have been refined over several decades to be more absorbent, slimmer and less leaky.
