Humans have introduced more than 37,000 invasive species, many harmful, into biomes around the world, threatening a range of plants and animals, finds a new study from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Invasive alien species (IAS) are one of the five major drivers of biodiversity loss and the framework aims to “eliminate (or) reduce” their impact on the environment. Here’s a closer look at IAS as well as the other top causes of nature loss identified by IPBES, an independent body that aims to help states sustainably manage biodiversity.
