Documentary reflects on how Victorian botanists began to remodel a barren ocean outpost, but omits some crucial environmental and social questions

From the dark belly of the ocean rises Ascension Island, a rocky outpost in the Atlantic Ocean born from volcanic eruptions and sediments accumulated over millions of years. While its formation feels like an act of cosmic creation, much of its landscape is human-made. During the Victorian era, British botanists brought plants to be cultivated locally, transforming a once barren land into a green oasis. Using this example as a starting point, Kevin Brennan and Laurence Durkin’s unhurried documentary contemplates the evolution of “terraforming,” a much-theorised ecological process in which humans alter a hostile environment to their needs.

Visually, this film unfolds in a series of static vignettes, which largely capture the natural topography of Ascension. Cracked lava fields and golden sands give way to lush forests, conjuring a striking colour palette of black, yellow, and green. The images are poetic, showcasing a stunning variety of flora and fauna; people are rarely seen on screen, their absence adding a touch of eeriness to the atmosphere.
