**1. Introduction**

The media fulfill the triple function of educating, informing and entertaining, acting as agents of socialization and as channels for the Informal Education of citizens. In the case of Environmental Education, the role of Environmental Journalism should be highlighted, because it is an area of specialization that has a marked didactic function, since it not only informs and denounces damages and attacks against nature, but also seeks to educate and raise awareness among citizens, so that they become committed to the conservation and defense of the environment (Esteve and Fernández del Moral, 1999) [1]. One of the genres most commonly used in Environmental Journalism to the compliance of these functions is the documentary. It is a genre that has a double informative and didactic aspect, which addresses the issues in depth, from multiple viewpoints and in a critical manner, with the aim of making the public reflect on them (Rabiger, 1989) [2]. These characteristics make the documentary an appropriate informal educational resource for the environmental awareness of citizens.
