Contamination of marine and terrestrial ecosystems by microplastics is putting individual organisms at risk.

Both macroplastic items, such as bags, bottles, and other packaging, and products containing micro- and nanoplastic particles—from cosmetics to paints—contaminate the Earth’s ecosystems.

Lab studies suggest that plastic pollutants in the environment could have detrimental effects on animals’ physiology.
