Past Year Question Essay PART A Public Awareness is the Key to Fight Pollution Pollution in the most basic form littering of rubbish or clogged drains to that of higher level such as dumping of hazardous waste and illegal logging, is chiefly attributed to lack of public awareness, so contends Minister of Natural Resources and Environment. As Malaysia joins the ranks of industrialized nations, pollution is fast becoming a menace that the country has to cope with. No amount of law can succeed in deterring people from polluting the environment so long as they are unaware about the adverse consequences of their action, he said. Although we have come down hard on the culprits, we can never be satisfied as we keep on raising the bar by benchmarking against developed nations in the likes of Japan, Sweden and New Zealand where every citizen is fully aware of their role in environmental preservation, he adds. As for water pollution, once a source of drinking water, many rivers in Malaysia have become dumping grounds for various types of hazardous wastes. Of all natural resources, water is the most severely threatened by pollution in this country. In 2006, gypsum, oil and hydrocarbon, dross, heavy metal sludge, mineral sludge and e-waste were the main categories of waste produced in the country. Of the total wastes produced, 110,814 metric tonnes were treated and disposed at Kualiti Alam Sdn Bhd, 9,360 metric tonnes (0.8%) at Trinekens (Sarawak) Sdn Bhd and 11,364 metric tonnes were incinerated at licensed off-site facilities.
