Tourism and Health Concerns Rise as Air Pollution Plagues Northern Thailand

High levels of air pollution in Thailand's northern city of Chiang Mai and surrounding provinces are causing a drop in tourism, with hotel bookings at only 45% occupancy. The government has urged residents to avoid outdoor activities and wear masks to filter particles. The air quality index reached 289 in March, 19 times over the World Health Organization's recommended level. Authorities blame forest fires and crop burning in Thailand and neighboring countries, and the prime minister is coordinating with Laos and Myanmar to reduce hot spots in the border area.
