More About This episode

The dry season has just begun in one of Africa's great ecosystems. Due to El Nino conditions, the drought will be more intense than usual. As temperatures soar, each day gets harder to survive. Creatures large and small must battle for precious resources. For some animals, like the world's largest population of hippos, drought is an existential threat.
