Plastic microparticles have now been found in rainwater, meaning our atmosphere contains tiny pieces of trash that originate from our industrial society.  Our oceans, rivers, groundwater, and now air are polluted with plastic. 

These materials are not inert, but disrupt endocrine function, meaning they alter our hormones and can create an increased risk of cancer.  They are becoming so ubiquitous that we eat, drink, and breathe our own trash.
