Microplastics

Microplastics are tiny pieces of plastic, smaller than 5mm (a grain of rice or smaller). They can come from intentionally made products, such as glitter, which is called a primary source, or from larger plastic items that have worn down over time, such as broken plastic containers, which are secondary sources. Microplastics can be found across the world, including in plants, animals, and people, as well as our physical environment. Because plastic does not easily break down in the environment, microplastics can build up in the environment for decades. They can be harmful to wildlife by blocking digestion, transferring other harmful chemicals via contact or ingestion, and cause physical damage. Similarly, there are concerns about the various human health risks posed by microplastics through ingestion and inhalation.
