Think of the last time you cleaned your home. You put some of your belongings in drawers, some in closets. Your largest possessions may fit only in the garage. No matter how many drawers you have, you couldn't fit a set of skis or a bicycle in them.
Wildlife habitat is another kind of home.
All animals need space to survive. While squirrels and house finches don't need much room, animals such as black bears and pronghorn antelope require lots of space where they are not often disturbed by people. In the Southwest, much habitat for these animals has been split into fragments by fences, roads, and other barriers. Pronghorn are reluctant to jump over fences. Numerous animals are killed as they cross roads.
