Counting down to help the earth. Your kids can count backwards and learn about recycling at the same time as 12 crocodiles carpool, 11 tigers don't let the water run, 10 otters organize the recycling bins, etc. The last few pages talk about recycling in depth, great for older kids who want to know more. A good book to introduce and reinforce caring for the earth starting at preschool age.
