Warmer temperatures under climate change are expected to further drive the expansion of invasive species. Invasive species are plants or animals, often moved around by human activity, that take hold in an environment with deleterious effects. ERADICATING INVADERSAbout three-quarters of the negative impacts from invasive species occur on land, especially in forests, woodlands, and farmed areas. Getting rid of invasive species once they are established, however, is difficult. Last December, the world's governments committed in the Kunming-Montreal Global Biodiversity Framework to reducing the introduction and establishment of priority invasive species by at least 50 percent by 2030.
