Where Did The Animals Go?

I grew up in a house on the edge of a forest, with a dirt road and not many neighbors. Hunters used to cut through our backyard to get to the woods in order to shoot animals. My little sisters and I put up signs with messages such as "No hunting!" and "Don't kill animals!" That was 45 years ago. I recently looked at my childhood home on Google Earth and was shocked to see that a new housing development had disseminated the forest. My sisters and I never envisioned a greater threat to animals than those hunters, but their impact pales in comparison with all those houses. Where did the animals go when they lost their homes?
