As they span significant areas of Asia, Europe and the Americas, karst landscapes cover some 15 percent of the Earth’s land mass. Scientists estimate that these areas of porous bedrock are home to as many as 1.5 billion people, a quarter of the global population.

Although caves and karst landscapes often serve as a destination for fourth grade field trips, they certainly have direct relevance to the 1.5 billion people who live in karst regions -- many of whom rely on karst aquifers for drinking water.

Scientists who study caves and karst landscapes are like all researchers. They look for data that addresses the broadest and most significant questions possible. It turns out that caves do a good job of providing significant answers. Those that contain animal fossils and records of ancient humans, for example, have been shown to have great value for understanding climate change and past environmental conditions.
