Eco Heroes Save The Climate for elementary grade kids. Experience this fun, song-filled celebration of nature with Hippo Works's eco-friendly cartoon animals. Go on an adventure with Simon the Hippo and friends as they learn about the world's changing climate, the role of carbon dioxide and methane, and the good eco-habits we can all develop. Along their way the animals find out about topics such as the greenhouse effect, the food chain, the "three Rs" (reducing, reusing, recycling), composting, and carbon offsetting.
