Why is it important to wash your clothes after caving?

Washing clothes after caving is important to prevent the spread of diseases like white nose syndrome, which can be harmful to bat populations.

What is the term for the scientific study and exploration of caves?

The scientific study and exploration of caves is called speleology.

What is the world's deepest cave, and where is it located?
