As the CEO of WildlifeDirect, Paula Kahumbu has dedicated her life to saving space for wildlife to thrive in Africa and building healthy relationships between humans and wild elephants. Paula got her start in wildlife conservation by measuring Kenya’s stockpile of elephant tusks confiscated from poachers—12 tons in all. And it turns out poachers aren’t the only threat to this endangered species.

National Geographic photographer David Guttenfelder is no stranger to dangerous situations. After graduating from college, he left his life in rural Iowa to cover the 1994 Rwandan genocide, an experience that kicked off a decades-long career of reporting on war, conflict, and major news events all around the world. But when the COVID-19 pandemic shut down travel to most countries, he took an assignment close to his roots—paddling the treacherously unpredictable waters between the Apostle Islands in Lake Superior. He describes what it was like visiting historic lighthouses and sea caves, and shares some surprising lessons he took away from that experience.

With 224 million people, Nigeria is Africa's most populous country. By 2050, it could crack the global top three with some 375 million people.

There are more than 8 billion humans on Earth, according to the United Nations. And for decades, China has had more people than any other country. But now, China’s population is declining. As soon as this year, it could lose its place as the most populous nation in the world. National Geographic photographer Justin Jin shares what he observed in this pivotal moment for China; he captured scenes where many young women are choosing not to have children, and instead are spending their money on doggie daycare and on karaoke nights with friends and male escorts. As we head into Women’s History Month, we’ll explore why Chinese women are taking a different path, despite the government campaigns pushing them to get married and have children.
