What If Every Volcano on Earth Erupted At Once?

Every single volcano. All 3 million of them. All at once. That's not a movie plot! Earth has come dangerously close to this before, and what happened nearly wiped out all complex life on the planet. In this video, you'll discover what the first few minutes actually feel like, why the sky changes color before anything explodes, how a single gas called sulfur dioxide becomes the slow weapon that kills the food chain, and why the safest people on Earth in this scenario might be sitting in mine shafts and submarines. You'll also find out how close humanity came to being erased the last time something like this happened and what that says about the world we're living on right now.
