Every organism on the planet has evolved specific adaptations to survive in their home range! In this class you will learn about the pressures the physical environment puts on organisms to adapt to heat, cold, water availability and changing light conditions. You will also learn how organisms interact with each other for food, to reproduce and as hosts, all of which determine their geographical distribution. Over millions of years, these interactions lead to competition and ultimately to the survival of the fittest. The overall result is the biodiversity we see today. But this biodiversity is under increasing threat from human activity, such as climate change and habitat destruction, and needs protection in conservation programs. You will learn how humans have shaped our planet and what the future holds for all organisms.
