Forests in Uttarakhand region of India are burning for months. Since February, these fires have destroyed thousands of hectares of forest. Dry conditions combined with high temperature and strong winds have facilitated the fires to spread in the entire region (Travel India).
Smoke from the fires have filled the entire valley and spreading in surrounding regions, reaching to Delhi and other highly populated areas. This is a huge concern for the rising air pollution level in the region. Air Quality in many urban and rural area has been reached to a hazardous level.
