The gorilla is one of Earth's most awe-inspiring creatures, yet it is also one of its most threatened. Find out why some people are making it their mission to try to save gorillas, and what readers can do to make it their mission too in this call-to-action series. Mission Survival explores why humans are endangering gorillas and their biomes and how and why some people have devoted their careers to helping save them. The series includes case studies that explore the work people are undertaking to save gorillas and "how-to" career guides that show children how they can build their own careers in animal conservation.
