Massive changes in animal populations are taking place in these times. They may be inconvenient to us, but extreme public alarm around the threat to agriculture posed by growing numbers of lanternflies in Pennsylvania, my current home, or the loud intrusion of crows moving into urban environments like the city of Timișoara in my native Romania often obscures the larger human cause of such changes. In the case of the crows, that means habitat loss via human encroachment leading them to seek a new home.
