What causes plastic pollution?
Plastic pollution in the ocean is a growing environmental crisis caused by human activities.
One of the main reasons for this pollution is improper waste disposal. Many plastic items, such as bottles,
bags, and packaging, are not disposed of correctly and end up in waterways. When plastic waste is littered on streets or
dumped in landfills, rain and wind can carry it into rivers and streams, which eventually flow into the ocean. Once in the water, plastic does not break down easily.
Instead, it remains for hundreds of years, breaking into smaller pieces called microplastics that continue to harm marine life.
Another major cause of plastic pollution in the ocean is fishing-related waste. Lost or discarded fishing nets, lines, and traps—also known as “ghost gear”—contribute significantly to the problem.
These materials are often made of strong, durable plastic that does not degrade, creating dangerous conditions for marine animals that can become tangled or injured.
Additionally, many fishers use plastic bait boxes, buoys, and ropes, which may accidentally fall into the water and contribute to pollution.
Single-use plastics, such as straws, food containers, and plastic cutlery, are also a major contributor. Many of these items are used for only a few minutes but remain in the environment for centuries.
Since they are lightweight, they are easily blown into waterways or washed into drains, eventually reaching the ocean. Furthermore, industrial waste and microplastic pollution from cosmetic products and synthetic clothing fibers add to the problem.
Overall, plastic pollution in the ocean is primarily caused by poor waste management, fishing-related debris, and everyday plastic use.
