Earth is the only planet we have–and for hundreds of years, people haven’t treated it very well. Even when it became clear that human activities harmed the water, air, and animals on Earth, people didn’t stop! However, there’s still ways we can help Earth. What’s more, many of the habits involved–recycling, reusing items, and not polluting–can be done by small children! In age-appropriate detail and language, this set introduces readers to the problems Earth has, but also ways they can help. Adorable, illustrated guides in each book talk directly to readers and keep the tone playful.
