Cooperation between zoos and aquariums towards prominent leadership in wildlife and habitat conservation is critical in the 21st century, for the world is now in an era of rising environmental threats, climate change and shrinking biodiversity. Zoos and aquariums are in the position to offer more significant contributions to the international response to crises through their fieldwork and research, and through educating more than 600 million annual visitors. Strategic co-operation will remove barriers for global conservation efforts and strengthen the ability of zoos and aquariums to promote proper animal management practices, conservation of wild population, field projects and public education.
