The most immediate is the environmental and health impacts from extracting crude oil, the production of plastic and finally, its longevity. A single fragment of plastic can last for four hundred to one thousand years. As it degrades, its chemicals leak into the ecosystem and up the food chain.
Additionally, plastics have varying degrees of recyclability. More...
