The UN Convention on Human Environment and Development, held in Stockholm, Sweden, in 1972, was the first collective effort to challenge environmental issues and crises. It addressed the world’s widespread concern with the participation of 113 countries, emphasizing the significance of educating and informing people regarding environmental issues. Subsequently, various conventions emphasized the importance of this issue and stated the traditional development models and the wasteful use of traditional resources and traditional ideas, in which economic growth is limited to quantitative indicators which disregard environmental protection and natural resources, could no longer meet the current and future needs of the world.
Since in the process of sustainable development, environmental education as a key lever plays a vital role in strengthening public participation, the Rio Convention emphasized the need to establish and maintain an educational movement with the purpose of changing and modifying public perceptions regarding environment, as an initial action for achieving sustainable development. Therefore, extensive measures should be taken to educate everyone from school age to puberty and adulthood.
