Here in Florida, many misguided souls spend countless hours (and expend much carbon) in a vain attempt at eradicating so called "exotic/invasive" species. Air potatos, kudzu, pythons, etc. will not vanish, and I for one am glad they are here. This peninsula is now more biodiverse than it has ever been in its entire evolutionary history, one of the few beneficial actions of H. sapiens has been the distribution and introduction of species to new lands. How is it that the only truly "invasive" and damaging species (our own) suffers from such myopia? Should we all dissapear tommorrow, Florida, and the rest of this planet would be far better off thanks to all those introduced evolutionary lineages that have enriched & enhanced communities and will continue to do so well into the future.
