The End-Ordovician Extinction was the first of the so-called ‘Big Five’ mass extinctions in the history of life on Earth - more than 80% of species in the oceans died out. But could you survive its aftermath? https://youtu.be/NbsdDga5gtw Listen to Eons: Surviving Deep Time wherever you get your podcasts! | Eons • PBS

How plants caused the first mass extinction🌱 480 million years ago, plants were emerging on landThey really thrived in an atmosphere high in carbon dioxideThis gave them the fuel to perform photosynthesis, sucking out CO2 and replacing it with OxygenThat paired with the weathering of the newly formed Appalachian mountains which also absorbs CO2 reduced global temperatures, leading to an ice age🧊 This is because CO2 is a greenhouse gas that traps heat in the atmosphereThese early plants were ve

Throughout Earth’s history, five major mass extinctions have drastically reshaped the planet’s biodiversity. The Ordovician-Silurian Extinction, approximately 444 million years ago, stands as one of the earliest cataclysms, eliminating around 85% of marine species. It was likely precipitated by a series of ice ages, causing significant drops in sea levels that disrupted marine habitats. The Permian-Triassic Extinction, known as the “Great Dying,” remains the most devastating event in Earth’s his
