This ecocritical book traces the environmental sensibilities of two Anglophone poets; Nobel Prize-winner Seamus Heaney (1939-2013), and British Poet Laureate Ted Hughes (1930-1998). Drawing on recent and multifarious developments in ecocritical theory, it examines how Hughes's and Heaney's respective poetics interact with late twentieth century developments in environmental thought, focusing in particular on ideas about ecology and environment in relation to religion, time, technology, colonialism, semiotics, and globalisation. This book is aimed at students of literature and environment, the relationship between poetry and environmental humanities, and the poetry of Ted Hughes or Seamus Heaney
