Gordon Buchanan starts his journey in Africa, where equatorial wildlife competes for space with a fast-growing human population. In Kenya, Gordon takes to the air to investigate the plight of flamingos and wildebeest, and joins an aerial team racing to rescue elephants from brutal attacks. In Uganda, satellite tech is helping a vast refugee camp become a thriving community. And in Gabon, illegal gold mines are detected from the air, while drones are deployed for a humpback whale health check.
