This virtual house is a lot like any other residence you'll find--from Alaska to Ohio to Florida. And inside are all kinds of things we use in our everyday lives. So take a look around and see what you can learn about how the way we live can affect our planet's biodiversity.

Just choose one of the categories above, hit "Enter House," and you'll be asked a question. Find the answer as you nose around the house clicking on items until you find the one that answers the question. Or, if you'd rather learn about one of the topics in more detail, hit "Click here to learn more about your topic" and go directly to that section of the WWF site.

Wipe your feet at the door, hang your coat in the closet, and come on in . . .
