Rising numbers of invasive species threaten global biodiversity and human livelihoods
In short: Researchers reviewing the impact of biological invasions found that the number of invasive alien species is increasing due to a more connected world and growing human populations. These species spread far beyond their native ranges, causing complex, long-term damage to environments and the essential services that ecosystems provide to humans.
The review highlights how invasive species disrupt everything from nutrient cycling to native species extinction. While some nations like Australia and New Zealand have seen success with biosecurity, the authors warn that many countries lack sufficient attention to the issue. The study emphasizes that effective management requires stronger international cooperation and better implementation of existing policy strategies.
Why it matters: Global connectivity is fueling an invasive species crisis that threatens the stability of our natural ecosystems.
