Hazards to caves include
Total or partial destruction by mining of limestone and gypsum, or by construction projects
Input of pollutants, through dumps and drip-water, which can contaminate groundwater drinking water resources very quickly and almost unfiltered. Consequently, the application of fertilizers or pesticides on agricultural land in karst areas is also very problematic.
Vandalism and overfrequency by visitors
Illegal excavations for archaeological, paleontological or mineralogical findings

The contribution of German cave and karst research to the UN Sustainable Development Goals (Agenda 2030)
The German Speleological federation (VdHK) is committed to the exploration and protection of underground ecosystems. This includes both their geodeiversity and biodiversity. This contributes to the Goals especially in the areas of land protection, biodiversity, water protection, tourism and education. In particular, these covers the following sustainability Goals "Quality education", "Clean water and sanitation", "Climate action", "Life on land" and "Partnerships to achieve the Goals".
The United Nations (UN) 2030 Agenda is a global action plan for sustainable development. It addresses major global challenges and provides a reference framework for the international community to jointly address the challenges and design solution strategies.
