Wildlife populations in the U.S. have experienced an astounding resurgence. But according to a recent feature in the Wall Street Journal, this encouraging eco-news has also meant a tremendous increase in the number and cost of human and animal encounters. The city of Columbia, South Carolina, for example, is spending $1 million to rid its drainage system of beavers and their dams, while an estimated 4,000 drivers in America collide with a deer every day! With some experts saying that in the Eastern U.S., more people now live in closer proximity to more wildlife than anywhere else on Earth at any time, it will be quite a wild challenge to deal with all our new furry neighbors.
