Ro Kumar had just finished college at UC – Berkeley and was watching the documentary Plastic Planet when he came upon a stunning fact: Every piece of plastic ever created still exists today. Even worse, every human has plastic and BPA in his or her bloodstream. Upon brushing his teeth with a conventional toothbrush shortly thereafter, he had an epiphany. In 2012, Brush with Bamboo‘s first bamboo toothbrush hit the market. Using sustainable, mold-resistant bamboo seemed like the natural alternative to the typical 4.7 billion landfill-clogging plastic toothbrushes that are tossed annually around the globe.
