Anyone can write a warrior poem, but not everyone can be a warrior poet. Warrior poetry is a perspective, a way of looking at the world. Warrior poets see things differently, and often see different things. There’s an activist side –make that earth (green) activist– that can’t help showing up in their poetry.
More people are starting to notice this, it seems. There are critical studies of Gary Snyder and a handful of other poets (Frost, Jeffers, Stevens), as well as some superb anthologies (top of the list being News of the Universe, subtitled Poems of Two-Fold Consciousness, edited by Robert Bly).
From this comes: Can Poetry Save the Earth? by John Felstiner, a Paul Celan scholar who looks at “green” poetry as acts of resistance, much as Celan’s poetry resisted the Holocaust.
