Among the most significant crises our planet faces as a result of human activity is the incessant pollution of our oceans, particularly by plastic waste. We have all heard the horror stories of aquatic animals getting caught in nets and choked by plastic bags, but another lesser-known problem is equally in need of urgent attention: microplastics. Making up the majority of trash in the oceans, microplastics come in multiple forms, including both pre-production pellets and debris from larger waste. They are a major health hazard for marine life because they are often mistaken for food and are quite harmful once ingested. It is possible for plastic pieces to clog the digestive systems of fish, causing them to starve, as well as to release toxins into their bloodstreams, including BPA, PCBs, DDT, and mercury. This can lead to organ inflammation, liver damage, and limited reproductive capacity, among other adverse effects. Microplastics make their way up the food chain from prey to predator, posing a possible threat to a wide spectrum of species, including humans, although its potential side effects are largely unknown at this time. What we do know is that people have produced plastic waste and handled it carelessly for decades, and the vast repercussions are beginning to become clear.
