The Impact of Plastic Pollution

Plastic pollution poses a significant threat to ecosystems worldwide, with its accumulation in water systems leading to catastrophic consequences. Larger plastics choke marine life, while microplastics infiltrate the food chain, affecting everything from fish to humans. The prevalence of microplastics, which are less than five millimeters in size, complicates filtration and contributes to bioaccumulation, resulting in increasingly harmful toxin levels as one proceeds up the food chain. This not only harms wildlife but also leads to health issues in humans due to the potential leaching of toxic chemicals from microplastics.
