Abstract: Allen Ginsberg, a brilliant pioneer in "Beat Generation" literary movement in the US, enjoys forever the honor brought by his masterpiece Howl, which is a representative poem both of himself and of the whole " Beat Generation" literature. Rich in connotations, the poem shows various significances, when put in different interpretive modes, among which ecological esthetics is one. Inheriting the philosophical tendency in Heidegger's existentialism, which disintegrates subject-object binary opposition, ecological esthetics attempts the systematical establishment of a harmonious and balanced relationship between humankind and generalized environment. Ecological esthetics predicts an ecological mode of the future marked by " order in disorder and institutionalization by de-institutionalization", which finds manifestation in Howl.
