摘要：

Plastics are used worldwide due to their durability and low manufacturing costs and a significant portion of plastic becomes waste that ends up in the ocean. In 2017 there were over 438 million metric tons (Mt) of plastics produced globally. Each year, 19-23 Mt of plastic wastes is estimated to leak into the world’s aquatic ecosystems and the ocean. In Tanzania, it is estimated that some 29,000 tons of plastic waste enter the ocean each year. This plastic waste leakage comes primarily from land-based sources due to the country’s weak solid waste management (SWM).
