In this February 4, 2017 photo, Maria Avila feeds her daughter Shomara in their family's adobe home in Coata, a village on the shored of Lake Titicaca in the Puno region of Peru. Avila grew angry as she talked about the lake’s contamination. “My ancestors have lived here more than 500 years. They have never gone through these things”, she said.
