Plastic pollution is one of the most pressing environmental issues facing our planet today. With millions of tons of plastic waste entering the oceans each year, the impact on marine ecosystems is devastating. This pollution affects marine life at all levels, from tiny plankton to large marine mammals, and has far-reaching consequences for biodiversity, human health, and the global economy. Plastic pollution originates from various sources, with single-use plastics like bags, bottles, straws, and packaging being major contributors. Improper waste management, littering, and inadequate recycling practices exacerbate the problem, while microplastics—tiny plastic particles less than 5mm in size—are created from the breakdown of larger plastic debris and products like cosmetics and synthetic clothing. Many marine animals, including fish, birds, and turtles, mistake plastic debris for food, leading to ingestion that causes internal injuries, blocks digestive tracts, and results in malnutrition or starvation. Entanglement in larger pieces of plastic waste, such as discarded fishing nets and six-pack rings, can cause injuries, impair mobility, and often lead to death, particularly in marine mammals like seals and dolphins. Additionally, plastics often contain harmful chemicals, such as bisphenol A (BPA) and phthalates, which leach into the water and accumulate in the bodies of marine organisms, disrupting endocrine systems, impairing reproduction, and causing developmental issues. Microplastics are ingested by a wide range of marine species, from plankton to whales, and these tiny particles can carry pollutants, such as pesticides and heavy metals, which can be transferred up the food chain, ultimately affecting human health. The presence of plastic pollution in marine environments disrupts entire ecosystems, with coral reefs being particularly susceptible. Plastic waste can smother corals, block sunlight, and introduce pathogens, leading to coral bleaching and death, and the loss of coral reefs has a cascading effect on marine biodiversity, affecting species that rely on these habitats for food and shelter.
