Which risk increases within karst caves when vegetation density above declines?

💡 Explanation

Speleothem growth declines because decreased vegetation reduces soil respiration, lowering CO₂ in percolating water; reduced dissolved CO₂ means less calcite precipitation via the bicarbonate equilibrium rather than structural effects because of limited connection to the surface load or different dissolution.
