This paper aims to compare the concept of otherness in Emmanuel Levinas and in Martin Buber. More precisely we would like to examine the possibility to apply the concept of otherness in environmental philosophy. The concept of otherness used by Levinas in his later work makes it complicated to apply this concept in the area of environmental philosophy. On the contrary Buber used the concept of otherness that requires including other entities to this concept (abstract entities and several material entities) and his philosophy is therefore more open to the application of this concept in the environmental philosophy.
