In this February 2, 2017 photo, a boy stands on a fishing boat on the littered shore of Lake Titicaca in Kapi Cruz Grande, in the Puno region of Peru. The camouflage-colored Titicaca water frogs that used to be in abundance have thinned in numbers and have been placed on a “critically endangered” list by the International Union for Conservation of Nature and just 10,000 remain.
