Plastics are found in the products we use every day: the toys we give our children, the clothing we wear, the disposable cups we drink from, the automobiles we make, the straws we use, the list goes on.  Cheap and easy to make, plastic goods and plastic production have exploded in recent years.  Yet the junked cars, the used straws and cups, they all end up somewhere, perhaps in a landfill, or perhaps drifting in the wind.  91% of plastic goods are not recycled.  Most have found their way to rivers, lakes, and oceans, and over time break down into tiny microscopic particles of plastic.  Microplastics are everywhere, even in the deepest sea floor sediments and in the Arctic.  They can originate in small form from toothpaste or makeup, or can be derived from larger pieces of plastic, which over time break down into small particles.
