Oscar Limachi, 48, a member of the local Qewaya community who works as a tour guide on Lake Titicaca, rides his boat early morning in search of a fishing site near Qewaya village, Lake Titicaca, Bolivia, July 3, 2018. "Fish used to live, eat and lay their eggs amongst these plants. Now there are no plants, so no fish," Limachi said. "We are afraid that someday the fish will disappear or migrate forever."
