Hippo Works dot com is a fun, creative way for kids to learn about being involved with global and animal rights causes. Created by cartoonist Denis Thomopoulos and two friends, Hippo Works dot com is colorful, attractive and easy to maneuver. I admire how the site's content can be just as relevant and fun for a 4 year old as it is for a 12 year old. Hippoworks encourages kids to learn more about the dangers of global warming, pollution and the extinction of animals through environmental concerns in addition to promoting global awareness. It's very educational.
