It makes a national historical collection, with references to some international events, of the environmental concerns marked by meetings held in several cities leading to the establishment of laws, decrees, ordinances that will minimize secular practices of environmental degradation, in order to contribute to environmental education historically contextualizing the course of the creation of our environmental legislation. The various regional, national and international movements show the concerns of the Brazilian people with the environment, even if in a first moment they may have been moved by what today is defended by the field of law as a diffuse right of the communities; being also responsible for the creation of numerous federal, state and municipal organs of defense of a public patrimony that has been degraded in the name of progress. This collection shows the concern of agencies, scholars, and common individuals about the future of life on earth, given the long period of anthropic degradation promoted over millennia.
