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. That's dangerous in the long run. Small, isolated populations are particularly vulnerable to disease and severe weather. Over time populations separated from others face inbreeding, which can also result in local extinction. These days conservationists in the Southwest and elsewhere are working to reconnect habitat drawers to make bigger wild areas.
