'the main causes that have been worsening air quality in Thailand.
Urban Transportation–especially in the metropolitan area of Bangkok. As the number of personal cars have increased over 250% in the past 20 years and the law to tax old vehicles that emit pollution is still relaxed. Plus, Thailand’s adoption of Euro Emission Standard (vehicle emission standard for pollution) is also delayed. SOLUTION - police!
Industrial Pollution–Thailand’s environment regulation has been weakened by the current junta government that does not monitor small factories compared to other countries who have legislation to mandate industrial pollution. Moreover, Thailand has been working blind on reducing industrial pollution as it has no data base on factory emission. SOLUTION - new Government
Forest Fires—The fires are directly linked to air pollution from SEA’s seasonal burning of agricultural waste for the next crop cycle. SOLUTION - police.
