National Geographic: Human Footprint Interactive

Find out how your daily choices of what to eat, drink, or read affect the environment. Five eggs a week adds up to over 20,000 in a lifetime, which amounts to about 57 hens laying eggs for an entire year! Little things add up and small decisions can leave a big carbon footprint. Compare the things you consume to what people in Britain, the United States, and Japan use. Then see photos and a video showing just how many of each item the average American consumes in a lifetime.
