Plastic Pollution Continues in Lake Malawi Despite Ban Lameck Masina MANGOCHI, MALAWI - Plastic bags continue to pollute Lake Malawi, despite a government ban on their use. Conservationists say the plastic is a threat to about 1,000 fish species found in the Africa's third-largest lake, and studies warn that the fish stock could be depleted by 2050 unless the lake is cleaned up. "You know when these plastic papers go to the lake, you find that fish are eating these plastic papers which is harmful to fish," said Force Ngwira, country director for Ripple Africa, an environmental NGO in Malawi. .
