Habitat Fragmentation

And there it was, 5 days after posting this:

"which brings up interesting ideas and thoughts about roads and habitat disruption and roads and human habitat disruption."

I found this in Traffic, by Tom Vanderbilt:

"In the same way that traffic has been blamed for habitat fragmentation of the wild, cutting off species from foraging areas or reducing the tendency of birds to breed, high traffic helps starve social interaction on human streets..."

Who'da thunk.
