The militant group Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya) on Friday held a “jogging and biking vs dolomite dumping” protest along the Manila baywalk in Roxas Boulevard, in protest against the Department of Environment and Natural Resources’ “beach nourishment” project which involves the dumping of crushed dolomite “white sand” along the 500-meter stretch of baywalk.
