Bangkok:The Bangkok Metropolitan Administration's Environment Department is urging the public to use natural materials for krathongs during this year's Loy Krathong festival. The department emphasizes the importance of avoiding bread, fish food, and foam krathongs, particularly in the ponds of Bangkok's public parks.
According to Thai News Agency, these ponds are closed systems, and the use of bread krathongs can lead to pollution. When bread disintegrates and sinks to the bottom, it pollutes the water, lowers oxygen levels, and severely harms the ecosystem.
The department encourages the public to celebrate responsibly by utilizing natural materials that are easy to collect or by participating in online Loy Krathong celebrations to ensure sustainability.
