This is not a question of one nation or two nations. This is a question of humanity. Our world is our home. There’s no other planet where we may move or shift.

The Dalai Lama on Tuesday urged strong global action to limit global warming and to protect fragile environments, including the Himalayan glaciers and Tibetan plateau.

Calling climate change a “problem which human beings created,” the 80-year-old Tibetan Buddhist spiritual leader said all of humanity was now responsible for taking action. But instead, he said, “we are relying on praying to God or to Buddha. Sometimes I feel this is very illogical.”

He issued his plea in a pre-taped video released as part of a campaign launched by the Tibetan government-in-exile in the north Indian hill town of Dharmsala, where the Dalai Lama has been based since fleeing a Chinese military crackdown in Tibet.

The government-in-exile said the campaign would continue through this year’s UN climate change talks, where nations hope to conclude a new treaty for limiting climate-warming gas emissions. The exiled government will also send its own delegate to the talks, which start 30 November in Paris, though it will not have a vote of its own.

“This is not a question of one nation or two nations. This is a question of humanity. Our world is our home,” the Dalai Lama said. “There’s no other planet where we may move or shift.”
