Ipoh karst, cave heritage under threat from development, say activists
In Perak's Kinta Valley, activists are raising awareness of the need to protect limestone karst landscapes and caves from uncontrolled development. Kinta Valley Watch's Ching Boon Tat is documenting the hills, while cave guide Mohd Zairis Abdul Rani highlights fossil and habitat discoveries. The inaugural International Day of Caves and Karst, declared by Unesco, is being marked today.
