Thai Environment Day
is celebrated on December 4. It is an official observance that was established in 1991. Although it is not a national holiday, it is widely marked with various events and activities.

On December 4, 1989, King Bhumibol Adulyadej held a birthday ceremony at the Grand Palace. During the ceremony, he delivered a speech on the problems of Thai environment. Main environmental issues in Thailand include air pollution, deforestation, overfishing, field and forest burning, lack of water resources, water pollution, poaching, and wildlife habitat loss.

The King expressed concerned about the future of the country's environment and called on Thai citizens to cooperate in order to solve environmental issues.

Two years later, the Ministry of Science, Technology and Environment designated December 4 as Thai Environment Day. Since 2002, the celebration has been coordinated by the Ministry of Natural Resources and Environment that was created that year.

Thai Environment Day focuses on raising awareness of environmental issues. On December 4, Thai citizens are encouraged to engage in eco-friendly activities, for example, plant a tree or ride a bike instead of using public transportation.

It should be recognized that when King Ramkhamhaeng declared, “there are fish in the ponds and rice in the fields” the situation of the environment both in Thailand and globally was less polluted and more robust. Much has changed in the present with the natural environment imperiled by unbridled industrialization, unceasing urbanization and related deforestation, the pollution of the natural factors for agriculture, and more importantly, the pollution of the air and water, resulting in global climate change, global warming, melting of icebergs, rise in sea levels, unexpected rainfall, landslides resulting from deforestation, apocalyptic-like flooding and uneven weather patterns.

The Assumption University of Thailand community is therefore urged and encouraged to help take steps to decrease Environmental pollution and to carry out actions of self-regulation and awareness raising towards the responsible use of natural resources so that small steps may help to save our Environment and ultimately life and the world itself.
