Plastics are not only bad for the environment, but they may also be bad for your health. Plastics used in toothbrush production, for example, may include dangerous and hazardous compounds such as BPA. Because BPA is an estrogen, it may be hazardous to human health. BPA is a hormone disruptor that has been linked to cancer, infertility, metabolic disorders, and other life-altering illnesses. Plastics containing BPA frequently produce tiny quantities of the toxin, but these levels can quickly escalate with repeated usage. Heat and repeated scratching, friction, or surface disturbance can potentially accelerate the release of BPA in some plastic goods. BPA is especially dangerous to the sick, the elderly, and young children.
