How do we make and break ecosystems?

Thanks to human activities, biodiversity is under threat. Non-native species, like rhododendron and parakeets, may help curb this threat by boosting biodiversity. But non-native species themselves are considered a key driver of biodiversity loss. Why? How can the addition of species result in a net reduction of species? And how can species that have evolved in entirely different systems outstrip native species that have evolved locally? Using case studies, logic and observations, we'll ponder how and why invasive species may be able to trump natural selection, beating natives at their own game
