Naked Hindu holy men, Naga saints, are going on a world tour to campaign against global warming.

The Express reports that “the Naga Saints – who smear themselves in ashes and share visions with marijuana pipes – are gathering in northern India’s spiritual centre Haridwar before beginning a world tour.

The sect – which shuns clothes and sex – says more than 250,000 followers will join the global crusade in London, Paris, Munich, New York, Beijing and Tokyo, according to the Austrian Times.

“We have decided to do our bit to save the planet from global warming,” said leader Shri Soham Baba. ”

According to the New York Daily News, the campaign will start during Kumbh Mela: “When thousands of naked Hindus speak, will the world listen?

That’s what the Naga Sadhus hope will happen starting later this month, when they spread their anti-global warming message during Kumbh Mela, the largest gathering of Hindus in the world.

The massive religious event in India is being used by the order, famous for their lack of clothing and coating their bodies in a layer of ash, in order to promote living green.

“Since the Kumbh Mela is the largest spiritual gathering, we have decided to do our bit to save the planet from global warming,” said Shri Soham Baba, Mahamandalesvara of Juna Akhara, said to be the commander-in-chief of the Naga saints, according to reports.

“There will be a huge presence of international communities and press during the fair,” he added. “We’ll utilize the occasion to generate a ’save the planet’ campaign worldwide.”

Their anti-global warming campaign will reportedly include signs with statements such as ‘Stop Global Warming, Save the Himalayas’ written in diferent languages. There will also be a photo exhibition created by the Naga that they believe illustrate the effects of climate change.

Thousands of Hindus are expected to attend the pilgramage, which attracts faithful from all over India, as well as the world. It takes place four times every 12 years, each time at a different location in India.”
