Take Pride Adventure Learning has partnered with the San Diego Zoo to create iKnow Animals Letters, and Sounds because we wanted to make a difference in global preservation and conservation effects. iKnow Animals Letters and Sounds builds a strong foundation for literacy and learning while supporting animals and the environment. A portion of all sales goes to worldwide efforts of preservation and conservation of animals an their habitats. Together we are part of the solution. For more than a quarter of a century, the not-for-profit Zoological Society of San Diego has celebrated significant breakthroughs in conservation and science for giant pandas, California condors, cheetahs, rhinoceros and other species. Such efforts in using conservation and science together have had worldwide implications in preventing the extinction of wildlife. Purchasing this product helps us achieve our conservation goals. We believe that even one endangered species is one too many.
