The current situation presents us with the need for a re-orientation of education towards a sustainable development, conscious and not rhetorical. In this paper, we will analyse some models and practices of environmental education that aim to go beyond sporadic experiences in green areas to create a new environmental awareness where a strong sharing of a common perspective is necessary to promote a new role of Humans with and in Nature. In order for this to happen it is a priority to acquire a mental and behavioural habitus that is continuous, profound and critical (UNESCO, 2021, p. 11) and not just a theoretical or occasional ecological speculation. In particular, the SentieriOutdoor project will be presented, which opens up the possibility of reconnecting with the environment through a time on a personal scale and allows us to rediscover the complexity of humanity in our relationship with Nature.
