What's for lunch? Flies! Delicious, if you're the EcoBot II. Ecological robots are energetically independent: they feed themselves by gathering their energy from environmental waste such as dead flies, sludge, and compost. Their only by-product is the carbon dioxide that would be released anyway by the waste products' decomposition. EcoBot can even find and obtain its own food. (But, sorry, getting EcoBot to clean your room is still years away!)
Of the three types of squirrels in the Sciuridae family of rodents, city dwellers are most familiar with the tree squirrel. From woodlands to city parks, you can see them scampering from branch to branch, a perfect example of a species that has learned and adapted to thrive in an urban environment. Grab yourself a pair of binoculars and have your own squirrel-spotting animal adventure.
Scott sent us a video about his family's farm, where they raise alpacas. Learn about what these domesticated herd animals are like, why the fiber that they provide is environmentally sustainable, and how an alpaca's raw fleece becomes yarn, from a kid who works with them every day.
