LAKE TITICACA, Bolivia (Reuters) - Isaac Callizaya, 39, grew up with the sound of waves lapping on the shores of Lake Titicaca, a giant body of water on the border between Bolivia and Peru that at 3,800 meters (12,500 ft) above sea level is the highest navigable lake in the world.
The island fishing community near Titicaca's southern tip that he was born into has seen big changes over the years. Many have moved away from the village on Pariti island, while urban sprawl from nearby cities has created a rising problem of pollution, altering the lake's landscape and forcing those that live around it to adapt.
