Impact of Invasive Species

The video discusses how animals and plants are distributed globally, both naturally and through human intervention. It highlights the impact of introduced species, such as the European starling and Burmese pythons, on ecosystems. The video also explores the presence of non-native species in urban areas and the sensitivity of island ecosystems to invasive species. It concludes with a call to learn from past mistakes and make better decisions regarding species introduction.
