<prompt> Ke koluoa efe e mpe ka ho fetisisa e kileng ea oela Lefatše?nan  <response>: Instruction in English: What is the worst disaster to ever befall planet Earth? . Response in English: One of the worst disasters to ever befall planet Earth was the Permian-Triassic extinction event, also known as the Great Dying, that occurred about 252 million years ago. It is considered as the most severe extinction event in Earths history, with up to 96 of all marine species and 70 of terrestrial vertebrate species becoming extinct. The event is thought to have been caused by a number of factors, including volcanic activity, climate change, and the release of methane from the ocean floor. The recovery of life on Earth took millions of years after this event. .

E nkoa e le ketsahalo e matla ka ho fetisisa ea ho timela historing ea Lefatše, me hoo e ka bang 96 ea mefuta eohle ea leoatle le 70 ea mefuta ea liphoofolo tse phelang lefatšeng e fela. Ho nahanoa hore ketsahalo ena e bakiloe ke lintlha tse ngata, tse kenyelletsang ho foqoha ha seretse se chesang, ho fetoha ha maemo a leholimo, le ho ntšoa ha methane botlaaseng ba leoatle. Ho hlaphoheloa ha bophelo Lefatšeng ho ile ha nka lilemo tse limilione ka mora ketsahalo ena.
