Explanation: This would be a huge problem. Right now, it's lurking right underneath the surface and a lot of us don't even know it's there. If it goes, it won't just be a big problem for the United States but the word will be in trouble. It will end life as we know it on earth.
The Yellowstone Caldera is one of four global calderas and a caldera is a mega volcano. It will definitely erupt but when it goes, it will lead to global extinction of the majority of the biological life on earth.
Now, it could go tomorrow or it could go in 50,000,000 years. We simply don't know when it will erupt.
We have a lot of power as a species but this is one of those things that we can't control at this moment and we can't mess with mother nature.
