Humans have exploited karsts for a variety of products and services, but unsustainable practices have caused population declines and extinctions among siteendemic taxa. Limestone quarrying is the primary threat to karst biodiversity in Southeast Asia, where quarrying rates exceed those in .
Weathering is the breakdown of rock by physical, chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater, which contains a weak carbonic acid, reacts with limestone. This causes the limestone to dissolve. Carbon dioxide from the respiration of animals (and ourselves) is one cause of increased carbon dioxide in the atmosphere.

Karst landscapes. The word ''karst'' comes from a German word used to describe the stony limestone landscape present in the northwestern Dinaric Alps in the country known as Slovenia. It is the distinctive surface and underground landforms such as caves, fluted rock outcrops and dolines or sinkholes that the term ''karst'' implies.
Limestone is less resistant than most igneous rocks, but more resistant than most other sedimentary rocks. It is therefore usually associated with hills and downland, and occurs in regions with other sedimentary rocks, typically clays. Karst topography and caves develop in limestone rocks due to their solubility in dilute acidic groundwater.
The steep, inaccessible nature of karst landscapes means that many limestone hills have retained their forest cover, even while the surrounding areas have been deforested. As a result, these striking towers act as natural refuges for species that have been wiped out from much of their range, such as the Tonkin snubnosed monkey, cao vit gibbon ...
