What are the threats to limestone environments?
Although karst caves and towers can take millions of years to form, they can disappear very quickly— taking entire ecosystems with them when they go.
Limestone is very valuable to humans; it’s a key ingredient in the manufacture of cement, concrete and mortar, and a commonly used material for buildings and stonework. Industrial-scale quarrying continues to represent a serious threat to limestone environments around the world.
Many species found in limestone ecosystems are so precisely adapted to their habitat that they cannot withstand changes, and they cannot survive outside their own small range, which may be as restricted as a single cave. The existence of such species is already precarious, which is why it’s so important to protect their habitat from degradation and destruction.
