Plastic pollution in oceans has severe ecological impacts, affecting marine life through ingestion and entanglement. Sea creatures, such as fish and birds, mistake plastics for food, leading to malnutrition or death. Additionally, microplastics disrupt the food chain, influencing various trophic levels. The accumulation of toxins associated with plastics can also lead to bioaccumulation and biomagnification, harming not just wildlife, but also human health through seafood consumption. Overall, plastic pollution threatens biodiversity, disrupts marine ecosystems, and poses significant challenges for conservation efforts.
