Plastic pollution is a growing global environmental crisis that is profoundly impacting our oceans, wildlife, and human health. Over the last several decades, global plastic production has exploded, with the vast majority of this plastic ending up as waste in landfills, incinerated, or leaked into the natural environment. Only a small fraction is successfully recycled. This rampant plastic pollution is having devastating consequences across marine ecosystems and poses risks to human health that are still being uncovered.
