This work deals with the importance of ecological in Dulce María Loynaz’s work. It is an approach to the Caribbean poetry as a search for one’s own voice and as an expression of a culture that is debated between dialogue and tension: both between literary processes and traditions (such as renouncing as echolism) and between civilistic and historical processes (the development of the First World as a cause of environmental degradation, not only the third world, but also global). In addition, it is stated how, in Loynaz (in Games of Waters. Greens of water and love (1947), where the analysis was centralised) the ecological aspect is ethical. Nature is not merely a contextual framework, which lends climate to subjective conditions, but, poem to poem, nature is in principle becoming metaphysical, fundant of reality. Water is, for poet, the key to an undivided reality (especially in terms of technology). Able to take all the forms and states of the material and the immaterial, it is therefore multiplicity and in its entirety, and in this respect it is not possible to dispense with interpretation (rather than this poetry: of this poetic) of the well-known considerations put forward by M. Heidegger in several of his works. Finalmente-and already in the context of a redefinition of literary genders is proposed to poetry as a true model of linguistic ecology.
