Environmental education towards sustainability is a permanent acting purpose which seeks to change the relation between individuals and other environment elements. Moreover, it highlights the interdependence of the human life processes and the environment where they occur. This paper concerns to an environmental education experience report during an internship for graduation at Psychology for the Universidade Federal do Rio Grande do Norte, Brazil. The internship happened in 2008 and was bound to the Program for Sanitary and Environmental Education of the Cidade Nova Neighborhood (PESA), which is a community at Natal, located at Northeast Brazil. This work was related to an effort that has been done, in a Brazilian context, to insert human sciences professionals in a practice which is traditionally directed to healthcare and social professionals. Furthermore, it tries to emphasize the relation between environmental problems and public healthcare and the interdisciplinary possibility as a way to manage this reality. As an environmental education purpose, the experience gathered an action set that aimed to long term effects for the local and global environment preservation, with the locals implication on thinking and action, according to their realities. The neighborhood environment interest is justified because it gathers a share of an environmental protection zone and it has a high parasite-related and infection-related death toll due to poor sanitary conditions. Also, there are flooding zones located at the neighborhood, due to garbage on the streets and to a poor forestation. Thus, this program has as goal to continually educate the community, seeking to allow the social awareness and mobilization towards neighborhood environment defense and preserving. Regarding these objectives, the actions done at the internship year that I intend do show are as follow: Environment Gymkhana with neighborhood schools students, Friendly Sidewalks, Photography and Environment Workshop in a local slum and the creation of a drumming group with children from said slum. The gymkhana’s theme was dengue fever and the related environmental problems and we asked questions about knowledge on environmental care for the disease prevention. As for the Friendly Sidewalks, they are talking groups with locals in every part of the neighborhoods, in their own houses, to discuss the main local environmental problems and possible solutions. To them we presented the PESA and suggested that they evaluate the local environmental status to relate such conditions to their own health. The aim of the Drumming Group and he Photography Workshop was to create a dialogue link between locals and professionals regarding the slum environmental condition, to further accomplish other actions in a space with minimum life conditions. Some of the results of the Friendly Sidewalks works included: cleansing of some streets, residents grouping to complain to city departments responsive for paving and draining, tree planting and monitoring of the main waste producers of the area. At the workshop, the photographic material was miscellaneous, with pictures showing sewage on the streets, lacking of hygiene on food handling, waste concentration at the streets and people disposing of this trash. These pictures were discussed in groups and shown to the whole community. All of the exposed actions shown themselves as useful in a community context as they allowed residents to become protagonists in pointing the problems that affected them the most and to discuss solutions, in addition to ease the creation of a contextualized knowledge about the local environment.
