RE: Nature or us? Who's our worst enemy?
The primary threat here in Virginia, aside from hunters, is cars. Here's a stat for ya: in 2005, there were approximately 5,000 dear-related vehicular accidents in Fairfax County, VAalone (it's a big county, but still). This includes accidents where no deer were hit, but where drivers swerved to avoid deer and hit a tree, another car, etc.
