An Arhuaco Indigenous holds their traditional "Poporo," a small dried gourd containing lime made from crushed seashells with which they boost the alkaloids of the coca leaf that they chew continuously, in Nabusimake at the Sierra Nevada de Santa Marta, Colombia, on February 11, 2024. Under a huge sacred tree, the wise Indigenous Arhuaco people chew coca and reflect on the future of Colombia's mythical Sierra Nevada. Their home of snow-capped peaks by the Caribbean Sea suffers from global warming and the violence of armed groups. (Photo by Raul ARBOLEDA / AFP)
