Encore events let you relive past performances in AltspaceVR. You'll experience the event exactly as it happened—emojis and all—but without the ability to interact with performers like you would at a live event. Come watch the first episode in a new series by Singularity University, hosted by Raymond McCauley. This episode, Welcome to the Sixth Great Extinction Level Event, covers climate change, ocean acidification, clear-cutting forests, and tag-along invasive species. Can conservationists do anything except wring their hands and catalog the lost species?
