TRANSCRIPT
Losing Streams• Streams in karst areas sometimes lose large volumes of
surface water through gradual loss into underground caverns.
Environmental Concerns with Karst
More Concerns• Cow manure in streams can lead directly to underground
cavern systems.• Sinkholes were often used as garbage dumps that
contaminate well water.• Septic tanks can fall into a sinkhole and cause major
pollution damage.
Speleothems: Organisms that are specially adapted to live in caves.• Often do not have fully developed eyes. Why bother?• Can’t photosynthesize food (no sunlight). No
photosynthetic organisms in caves.
