Abstract — The idea of sustainability in the Brazilian Agenda 21 requires governments and institutions to be attentive to good planning and formation of alliances in the performance of actions, should seek a better quality of life for the population. Thus, the objective was to understand the importance of the teaching practice focused on Environmental Education, in an interdisciplinary and contextualized way, in public high schools in the municipality of Itacoatiara - AM. This is a bibliographical and descriptive documentary research. Data were collected in the secretariats of three state public schools, a group of 35 senior students were asked to formulate and discuss issues involving topics of different subjects. It was found that only 5% of the students showed the interest aroused by teachers and local society for subjects such as Agenda 21 and related. However, 80% of them have been very interested in developing current issues such as those mentioned in Agenda 21. The rest seem to have no safe direction on the news they want to seize.

INTRODUCTION Agenda 21 is a document that involves participation in which society, governments, economic and social sectors seek to diagnose problems, understand the conflicts involved and agree on ways to solve them, in order to build what has been called and progressive sustainability (Agenda 21/2018).

It is known that high school is the preparatory phase for undergraduate courses, emphasizing that environmental awareness and behavior are factors that transcend the contents seen in the classroom. Therefore, there is a need to investigate the level of environmental awareness and behavior among students and teachers, as well as the possible influence of these aspects in the choice of a profession. According to Veiga (2010) there is an indication that Brazil has not yet been fully successful in applying the theme.
