Green activists from a human chain and leaflet distribution ceremony on Monday said the sound pollution control act 2004 was not being enforced in Dhaka. The Dhaka Metropolitan Police in the middle of last year took some steps, including campaign against sound pollution, but later it did not continue with programme, the activists said. Save the Environment Movement and Bangladesh Environmental Lawyers Association formed the human chain and leaflet distribution programme at Dhanmondi. SEM chairman Abu Naser Khan, coordinator Halim Dad Khan and others, including a good number of pedestrians, took part in the human chain.
