Like busy moles, we humans dig an awful lot of holes to get things done, in the ground, in our oceans, and even in our bathrooms! We dig holes in sandboxes to play games with friends, on ancient sites to discover awesome treasure and fossils, and on farms to plant the food we eat. Unfortunately, we also dig holes that aren't so wholesome--holes that rip apart the ground, spill dangerous chemicals, and permanently damage the earth. Going on this way means digging nature into a deeper hole, but used correctly, our shovels and machines might be able to help our planet instead of destroy it.

In whimsical rhyme and delightfully strange illustrations, these moles unearth the good and bad excitement happening beneath our feet, exposing our huge environmental impact and urging us to put our harmful ways back under construction.
