Lake Malawi, one of Africa’s most important freshwater ecosystems and a UNESCO World Heritage site, is facing a growing threat from plastic pollution. It’s endangering endemic fish species, tourism and the communities that rely on the lake. Since 2023, local divers in Cape Maclear have been removing plastic trash several times a week. Local residents say the difference is noticeable.

Scientists warn that microplastics from plastic waste can enter the human food chain through contaminated fish. While Malawi banned thin plastics in February 2025, enforcement remains difficult. Some of the recovered waste is recycled into products for sale, showing how local action can protect biodiversity, livelihoods and public health – and hopefully inspire wider cleanup efforts across the lake.
