By Jacqueline Mattos (@mattosjacq) In the last few decades, scientific observations have highlighted that we are now facing a mass extinction, caused in major part by human activity: habitat fragmentation, invasive species, spread of pathogens and diseases, climate changes leading to global warming, and, of course, direct killing of endangered species. However, this is still a debated topic among scientists. Some say that we are not in a mass extinction event, and that if we were, conservation biology and all the efforts we have been putting into conserving animal species…

By Jacqueline Mattos (@mattosjacq) Yes, we are in a mass extinction event Recent research has spotted a new major mass extinction, termed the “end-Guadalupian (259.8 Ma),” according to a scientific paper in the journal Historical Biology. Previously, scientists knew of only five mass extinctions in the history of Earth: the end-Ordovician (443.8 Ma), the Late Devonian (372.2 Ma), the end-Permian (251.9 Ma), the end-Triassic (201.4 Ma), and the end-Cretaceous (66 Ma). Our current biodiversity crisis has been called the sixth mass extinction, but with these new findings it will probably…
