Plastic Pollution and Its Impact on Marine Ecosystems

Abstract

The widespread and urgent problem of plastic pollution has become a major environmental concern in the modern era, endangering marine habitats and the species that depend on them. Mismanagement of municipal garbage, industrial discharge, and an inadequate recycling infrastructure are the main land-based sources of the 8-12 million metric tons of plastic waste that ends up in the oceans every year. When plastics enter the ocean, they break down into smaller pieces called microplastics and nanoplastics. These tiny particles are resistant to degradation and end up in every part of the marine food chain. Ingestion, entanglement, habitat modification, exposure to harmful chemicals, and absorbed pollution all have negative effects on marine animals, from tiny plankton to huge mammals. Disruptions to ecological balance and population decreases result from interactions that hinder eating, reproduction, and survival. Plastic pollution has far-reaching social and economic effects; it endangers human health and food security due to the bioaccumulation of microplastics in seafood and destroys coastal economies, fisheries, and aquaculture. The issue is still not fully addressed owing to rising plastic production, insufficient enforcement, and disparities in global capacity to handle it. Efforts to address it have focused on better waste management, international agreements, circular economy models, and public awareness campaigns. the causes, distribution, and effects of marine plastic pollution; the domino effect it has on marine life and human health; and the critical need for concerted, evidence-based policymaking and global collaboration to preserve marine ecosystems for the benefit of generations to come.
