How is Bhutan a carbon negative country?

Bhutan is a small country nestled between India and China, with an extremely small population. But as the world grapples with climate change, the world has reason to pay attention to Bhutanese people. Bhutan has ALWAYS been a carbon negative country, and it has a min 60% of forest cover as part of its constitution. The cross stitches of Buddhism, a compassionate monarchy and leaders, and living literally in the mountains, have all played a part in the progressive and people + environment-centric policies of Bhutan.  I spoke to Kinley Dorjee, an environmental science professor in Bhutan.
