There are many pressing environmental issues in Mongolian capital, Ulaanbaatar where half of the nation’s population lives. A Centre for Ecological Education along with an Arboretum have been established in Ulaanbaatar for providing know-how on planting trees; the new trees will help decrease fine pollutant dusts and absorb soil pollution. According to the study, one hectare of land planted with trees can purify 18 million cubic meters of air and absorb 30-35% of smoke. Woody plants reduce air pollution to 40 percent and also absorb 26 percent of noise in the winter.

The centre has stock of 40,000-50,000 saplings and aims to plant one million trees in near future.
