Invasive Alien Species
This image was generated by AI and may not depict real events.
Invasive alien species are causing significant harm to the environment, ecosystems, and biodiversity, and are considered a major driver of biodiversity loss. These species can outcompete native species, alter ecosystems, and even lead to species extinctions, making them a significant threat to global environmental integrity and food security.
Invasive alien species are introduced organisms that become overpopulated and harm their new environment. They affect habitats and bioregions, causing ecological, environmental, and economic damage. Invasive plant species can displace native species, reduce crop yields, and clog water bodies. Human activities, such as travel and trade, often unintentionally spread invasive species. Invasive species can prey on native species, outcompete them for food, and prevent native species from reproducing. The impact of invasive alien species on biodiversity varies by region, but can lead to significant alterations in native ecosystems and even species extinctions.
