Microplastics are tiny small plastics that form from the breakdown of larger plastic and result from commercial product development. Primary microplastics are purposefully manufactured and are used in cosmetics, textiles, and clothing.
Whereas secondary microplastics result from the breakdown of larger items such as water bottles, plastic bags, etc. Microplastics are very hard to break down and are known to be very detrimental to the ocean and marine life where it has been detected in whales, plankton, and commercial seafood.
