Cate Larson meets with geophysicist Njahi Mwangala while at IMAGE23 in Houston, TX to learn about her work with Geoscientists Without Borders, a non-profit that provides funding for humanitarian projects all around the world. Her project revolves around Lake Tanganyika, a massive body of water that runs along the East African Rift system, and its long standing sediment pollution problem that's drastically impacting the fish population and the fishing industry its surrounding countries rely on.
