But we can clearly see that the public are wrong about the rate of threatened species among those that are evaluated.\n\nAs of December 2024, the IUCN had assessed the threatened status of 166,061 species and of those 46,337 were classified as threatened (either critically endangered, endangered or vulnerable), which gives a percentage of 28%. (Those numbers also include fungi and protists, which are neither plants nor animals.)\n\nThe Red List uses a variety of criteria to assess the threatened status of a species, and focuses on the worst-case scenario, potentially overestimating the level of threat. The criteria are somewhat subjective and the decisions are secretive and in some cases there are political motivations to listing a species as more or less threatened than it is. Also, we humans tend to focus on where the problems are, so potentially when evaluating species for the Red List, those that are most endangered are being evaluated first, which would lead to 28% potentially being an overestimation, but nobody knows for sure.\n\nEven if different experts would assess the status of the same species differently, the 150,000 is such a large number that the disagreements would probably go in both directions. And even if 28% is probably an overestimation, it is definitely  “more right” than the other options of this question, which was confirmed by four independent biologists who we asked for feedback.\n\n[1]  [IUCN Red List, Table 1a](https:\u002F\u002Fwww.iucnredlist.org\u002Fresources\u002Fsummary-statistics#Summary%20Tables)","If you believed most of nature was threatened already, we think it’s useful for you to realize that two thirds of all animals and plants are NOT threatened, yet. One third is terribly high, but it’s still possible to reverse the trend towards mass extinction. A lot of conservation work is successful but much more is needed.\n\n### Why ask this question?\nWe have no intention of trivializing the fact that one third of nature is threatened! We hope to help focus on the fact that most people believe that the situation is even worse, which we think is problematic. We believe that this may cause resignation, as people lose their hope. We hope that promoting this fact helps people realize that there’s still a lot we can and should do to reverse the trend towards mass extinction. It’s not too late, which many people seem to believe.\n\n### Is it too late to save nature?\nIt's not too late to save most of nature. We humans have destroyed lots of natural habitats, but that can come to an end. Many [conservation efforts have succeeded](https:\u002F\u002Fwww.theguardian.com\u002Fenvironment\u002Fgallery\u002F2018\u002Fmay\u002F22\u002F12-conservation-success-stories-in-pictures), and with more hard work we can still save many of these species from going extinct.\n\n### Can I trust this fact?\nYes, but you should know the limitations of the data. Every year, biologists across the world study the situation of plants and animals across the world and they publish their findings on the [Red List](https:\u002F\u002Fwww.iucnredlist.org\u002F), where you can track the status of more than 160,000 species!\n\nThat is a lot, but it’s actually just 8% of all known species in the world, and nobody knows what share of all existing species are known.\nEven among the known species, 92% haven’t yet gotten enough attention to be fully investigated, mainly because it’s very costly to conduct multiple surveys of wild populations of animals and plants over time and track their decline. But new assessments of more species are still added every year, and with the additions to the list, roughly the same proportion is listed as threatened or endangered – around 28%. We have asked four independent experts to evaluate this question and they all agree that it seems correct.  \n","Nature is not lost yet","Most people exaggerate how many species are threatened. If you think almost all of nature is threatened you may easily lose hope and fail to realize what actions are needed to save the species that are actually threatened.","Most of nature is not threatened yet"]
