AIR POLLUTION
In 1984, there were health concerns with the great number of pig farms in Singapore. They were deemed to have contributed to the pollution of the country, namely to the air. This problem was solved by reducing the number of such farms. 65.8 metric tons (64.8 long tons; 72.5 short tons) of carbon dioxide were emitted in the country in 1996, ranking among one of the highest emission levels in the world. Air polluters in Singapore are mostly, but not only, vehicles for transport, despite the country's tough regulations. The country frequently is blanketed in haze, contributed by smoke from Indonesian fires. WATER POLLUTION
Water in Singapore is polluted by unwanted materials contributed by industrial facilities, coupled by oil from both incoming and outgoing trading vessels. Corrective measures are taken, and affected water is taken for treatment at specialised centres. Plants such as NEWater treat unwanted water into drinkable water. One major water body in Singapore which used to be polluted is the Singapore River.
URBANISATION
Singapore's rapid development into an urban nation has neglected the natural environment, according to a report published by the National University of Singapore, which ranked the country as the "worst environmental offender among 179 countries". The report was "slammed" by the Singaporean government.
DEFORESTATION
From around 1980 to 2010, Singapore lost approximately 90 percent of its natural forests as a result of urbanisation.
Environmental Issues in CAMBODIA:
Deforestation is the most serious threat to Cambodia’s environment. In the 1960s and 1970s Cambodian forests and wetlands were harmed by bombings and defoliants used in the Vietnam War. In the 1970s and 1980s the damage continued with the disastrous agricultural policies of the Khmer Rouge regime and civil war. In the relatively peaceful 1990s, timber became an important export for Cambodia. More than 800,000
