Climate Change is an urgent environmental issue. It’s about how we deal with our future life and the life of the future generations. To clarify our obligations to future generations, lots scholars approve Merleau-Ponty’s flesh ontology is a good option to build the theoretical framework. On the flesh ontology, we trace the line of thought that the flesh concept has followed and back to the temporality structure and I-other relationship. Merleau-Ponty finds we have met time in our structure of perception, time constitutes itself as a structure that past and future overlap through present in mutual harmony. This achievement makes it possible for us to beyond the limit of objective time, the limit of certain moment, and to face with the future. The temporality structure is an infinite whole, and we can assess the future not form the present, but from our dimension towards the future. With the help of temporality structure, Merleau-Ponty expands our personal life into the dimensions of collective history and social world, and finds other people as an actual potentiality of my life field, my coexistence. We can appreciate them from the same Earth which we share together. The body of other people as a form of behavior shows as the subject of a pattern of behavior, alien existence. Under another’s gaze, our subjectivity opens itself to other people and go forth from itself. Accordingly, we can go beyond the limit of our country and region, and concern with the strangers and descendants.
