Plastic pollution has become a major global problem, especially in coastal areas like Karachi, where marine ecosystems are in serious danger. This report aims to investigate the factors leading to plastic pollution in Karachi’s marine environment, focusing on Clifton Beach, and to suggest ways to mitigate its negative effects. The excessive accumulation of plastic waste in Karachi’s marine system, particularly at Clifton Beach, poses a serious threat to the ecosystem, marine life, and human health, requiring immediate action.

Karachi, the bustling metropolis on the Arabian Sea coast, produces a significant amount of plastic waste due to its large population and urbanization. Unfortunately, inadequate waste management infrastructure and a lack of awareness result in widespread plastic waste disposal into the marine environment. Clifton Beach, a popular recreational spot, suffers greatly from plastic pollution, which harms its biodiversity and ecosystem services.

Inadequate recycling facilities, improper disposal of plastic waste, and a lack of public awareness about the effects of plastic pollution are the main contributors to plastic pollution in Karachi’s marine ecosystem. This influx of plastic waste entangles and is ingested by marine organisms, disrupts marine habitats, and contaminates the water, posing health risks to humans through seafood consumption. A study by Khan et al. (2020) highlights the alarming levels of plastic pollution in Karachi’s coastal areas, including Clifton Beach, which has significant implications for marine biodiversity and ecosystem functioning.

Coordinated actions at the individual, community, and governmental levels are needed to reduce plastic pollution in Karachi’s maritime environment. Stricter laws governing the manufacturing and disposal of plastic, support for recycling initiatives, and public awareness campaigns can all help mitigate the harmful consequences of plastic pollution. Reducing the usage of single- use plastics and improving waste management through activities such as recycling drives, beach cleanups, and technological advancements are necessary to combat ocean plastic pollution. International collaboration is also essential to develop comprehensive solutions to safeguard marine ecosystems and the appeal of coastal areas.

Plastic pollution poses a significant threat to human health, marine biodiversity, and the health of the ecosystem in Karachi’s maritime environment, especially at Clifton Beach. Urgent action is needed to address this environmental catastrophe through cooperative efforts to minimize plastic waste generation, enhance waste management infrastructure, and promote sustainable habits to preserve Karachi’s coastal habitats for future generations.
