The environment and helping to keep it clean and running well is a passion of mine and I love being able to help kids realize the impact they make, while keeping it fun and not "preachy." No one wants to hear that "you should put that in the recycling bin, not the trash can" 150 times a day, but a book like this is great for getting the point across.
Human Footprint introduces the whole idea of what a person's footprint on the Earth actually is, in terms that kids can understand and actually be interested in. The facts are kept short and to the point and have an awesome impact that way.
Did you know that in your lifetime you'll use approximately 31, 350 gallons of gas. At almost $4 a pop, that fact hurts a bit.
87, 520 slices of bread, 28,433 showers, and the idea of Americans throwing out 694 plastic bottles a second will really make readers think about what they're doing to the Earth (not to mention their BODY) on a larger scale. Simple ideas for helping to lower our impact are interspersed with the more daunting facts, like fixing leaky faucets, not wasting food, recycling plastic bags, and unplugging electronics.
National Geographic puts out amazing children's non-fiction, you've seen lots of examples on this blog, and this one is equally impressive. The bold photographs add lots of visual interest, as do the bright colors used in fact boxes. If it looks dull, the kids aren't going to pick it up!
