“See you next year!” a Portuguese fire warden says as he dismantles his control equipment at the end of the season. Humans and nature in southern Europe may be used to forest fires, but that does not change the facts: The ever more massive conflagrations are caused by climate change. We have long been living in the age of fire.

In the Portuguese interior, a forest fire has just devastated a large area. Wounded nature is silent, not a single bird is heard, only the wind that makes the charred tree trunks rustle. But the vegetation recovers astonishingly fast. Where all life seemed to be gone, greenery soon sprouts from the ruined trees. The residents of the affected region are engaged in the reconstruction with great respect for their natural environment. Because plants, too, are sentient creatures. In quiet, almost melancholic, but also hopeful images, the film pays tribute to the strength of the trees and illustrates how essential it would be for humanity to learn to live in harmony with nature again.

A film that teaches us mindfulness. In his audiovisual diary, award-winning Swiss-Canadian filmmaker Peter Mettler says farewell to his mother and father. But the film transcends his personal work of mourning. In an always dialogue-oriented search movement over the cycle of life, he reflects on this world and the next, on existence and time. It is an eternal circuit and flow – like the continuous passing of clouds and rivers.

Visually as well as intellectually, Peter Mettler draws upon personal conversations, philosophical and spiritual texts as well as his own film and sound archive. His approach is characterised by openness and humility towards life and nature. This attentive attitude characterises the director’s notion of “film-making” per se that has shaped all his works. “While the Green Grass Grows” comprises two parts of a larger epic diary project with the same title.
