Every year, millions of tons of plastic waste find their way into the world’s oceans, creating one of the most urgent environmental crises of our time. From floating debris to microplastics invisible to the naked eye, this pollution threatens marine ecosystems and the countless species that depend on them. Plastic never fully decomposes; instead, it breaks down into smaller fragments that persist for centuries, contaminating the food chain and altering ocean habitats. Marine animals are among the most direct victims of plastic pollution. Sea turtles mistake plastic bags for jellyfish and choke to death. Seabirds feed plastic fragments to their chicks, filling their stomachs with indigestible waste. Whales and dolphins suffer from entanglement in discarded fishing nets and other debris, leading to injury, starvation, or drowning. Even microscopic plankton, the foundation of oceanic life, ingest plastic particles—allowing toxins to accumulate and spread up the food web to fish and event...
