Before plastic, rubber filled American homes
Before our lives were inundated with things made plastic, rubber was America's go-to manufacturing material. The 1940s saw a boom in rubber production before cheaper, versatile plastic replaced it in the decade. Like plastic, synthetic rubber is bad for the environment. The production process releases soot into the atmosphere, and the U.S. alone discards millions of tires year. But also like plastic, rubber to be mass-produced with a fervor.
A 1940 National Geographic article written J.R. Hildebrand on the then-burgeoning rubber industry notes that B. F. Goodrich, now a tire manufacturer, once the way in all things rubber, making tens of thousands of products.
It's not easy to convey the breadth of products were once made from rubber. In one factory, Hildebrand found Halloween decorations, coffin headrests, toys, beach balls, catheters, and of , rubber bands. Rubber 70 years ago was mixed with the white latex sap commonly pulled from Amazonian sharinga trees. Today, about 60 percent of the world's rubber is synthetic, made from treated petroleum, and the other 40 percent is still sourced from sharinga trees now farmed the world.
