Boats of fishermen are seen on the dried Poopo lakebed in the Oruro Department, south of La Paz, Bolivia, December 17, 2015. Lake Poopo in Bolivia, the Andean nation's formerly second largest after the famed Titicaca, has dried up entirely. With the water now gone, animals have died off in the millions, according to studies. And the local families, having lost much of their sustenance, have been forced to migrate.

Abdulahi Yaroow, 13, smokes a cigarette while chewing khat at the same time in Mogadishu August 10, 2014. Grown on plantations in the highlands of Kenya and Ethiopia, tonnes of khat, or qat, dubbed “the flower of paradise” by its users, are flown daily into Mogadishu airport, to be distributed from there in convoys of lorries to markets across Somalia. Britain, whose large ethnic Somali community sustained a lucrative demand for the leaves, banned khat from July as an illegal drug. This prohibition jolted the khat market, creating a supply glut in Somalia and pushing down prices, to the delight of the many connoisseurs of its amphetamine-like high.
