In Minecraft, danger comes in many forms. Most people attribute danger in survival mode to enemies like zombies and skeletons, which you can face at night or in dark areas of the map.

The truth is that the world itself is also dangerous due to random lava lakes that can be found while mining. In addition, traps and other things appear when you concentrate on collecting diamonds or other minerals below the surface. It's worth the risk as long as you're careful.
