Known as a poet of nature, Mary Oliver’s poetic oeuvre grows out of the literary foundations of Romanticism both in its relative linguistic simplicity and in its sense of wonder at life in all its natural forms and manifestations. The Romantics acknowledged the nature’s profound significance for human well-being and viewed nature as a transcendental phenomenon that links humans to God. The notion that nature is divine as it contains all life, and all of it equally worthy, resonates deeply in Oliver’s verses. The paper will focus on selected poems from her 2008 collection The Truro Bear and Other Adventures to show that Oliver’s poetry deals with ecological crisis in a singular way. An expression of her view of nature as magnificent, her poetry can stir an emotional response that pushes the reader toward a greater sense of appreciation of and the need for protecting nature. Rather than adopting a typically dystopian approach of the twenty-first-century eco-fiction, which hopes to mobilize readers by instilling a sense of fear through its representation of endangered nature, illnesses, and ecological crises, Oliver speaks of nature with awe and love. Relying on the tenets of affect theory, the paper proposes that by representing the beauty and wonder of life, by making her readers see and love what surrounds them, Oliver invites her audience to act positively as appreciation discourages destruction. In a radical change of perspective, people should strive toward what Iris Murdoch terms unselfing, and abandon unsustainable anthropocentric views and policies to become a caring human kind, willing to take “the chance to love everything.”
