"Like busy moles, we humans dig lots of holes to get things done: in the ground, in our oceans, and even in our bathrooms! Unfortunately, many of these holes rip apart the ground, spill dangerous chemicals, and permanently damage our earth. But used correctly, our shovels and machines might be able to help our planet instead of destroy. Whimsical rhyme and delightfully strange illustrations unearth the excitement happening beneath our feet and urge us to put our environmental destruction back under construction."--Page 2 of cover.
