A recent thought-provoking piece on the Owen Sound Hub concerning invasive species: Who’s Invading Whom. Invasive species may not be as black-and-white and issue as some might think… as one commenter remarked, “The worst invasive species is Homo sapiens.” Semi-related, another article from Owen Sound Sun-Times in July: Giant hogweed not the giant boogeyman, says weed inspector.
