Plants, animals, and entire ecosystems that took tens of thousands to millions of years to evolve are at risk. What is being gained in their place? A hodgepodge of species found in other parts of the world. . . . Florida is being homogenized, and everyone, for all time to come, will be the poorer for it.”
