Celebrated as a writer first, American scientist Rachel Carson is recognized as the “scientist-poet of the sea”. But it is her final text Silent Spring, which cements her name in the American if not global psyche, for this “activist longform journalism”, building on “the genre’s method of civic engagement” is said to have helped launch the modern environmental movement. Ten years before the term “ecofeminism” is coined, Rachel Carson displays a vivid intersectionality to her writing. This paper argues that as such, her application of scientific questing connecting birds, humans, and the ecosystem in the scientific literary journalism narrative of Silent Spring positions her in the genealogical vanguard of the ecofeminist movement—the links are evident. With what we know already and further learn about climate change every day, this paper pays retrospective homage to a prophetic and gifted long-form narrative writer, specifically focusing on her use of poetry and long-form language technique; a female marine biologist at a time when to be a female scientist was a feat in itself; and an intellectual and assertive, yet gentle activist who affected deep change against the prevailing cultural tide of male dominated politics, business, and science at the time.
