The world faces a conservation crisis that is at once urgent and enormous in scale. Zoos and aquaria can make a powerful contribution through nutrition science and research. Good nutrition saves animals from extinction. Nutrition research is vital in helping characterise and solve the challenge at hand. Since the publication of the World Zoo Conservation Strategy, a littele over ten years ago, research in zoos and aquaria has expanded in scope, quality and importance. Despite this surge in research efforts worldwide, zoos and aquaria must do even more over the next ten years.
