Researchers warn that human impacts on the environment are fuelling the global spread of animals and plants, which are replacing regionally distinct species.
Known as "biotic homogenization," it's a phenomenon that "elicits serious concern among conservationists as a major threat to regional individuality," according to University of Wisconsin biologist Julian Olden.
Olden is among a small but growing number of scientists investigating a process he likens to the "rapid spread of big-box retailers" at the expense of local "mom-and-pop businesses."
"We are just starting to understand the subtle aspects and implications of biotic homogenization," he added.
As long as I don't have to see that little bouncing happy-face in my backyard, or hear "Attention Wal-Mart picnickers..." when I'm at the park.
