The 2016 WHO press release indicated that environmental unsanitary conditions cause 12.6 million deaths per year. This alarming number of deaths is enough to justify the imperative need to fight against any source of insalubrity on a planetary scale. One of the effective strategies for combating any form of insalubrity is the MEEMSAL (an acronym for “Mon Espace d’Evolution Mon SALon”) theory. According to this theory, the eradication of insalubrity and all other forms of anthropogenic pollution must start at school by training learners in eco-citizen education. It is demonstrated in this work that the application of the foundations of the present theory makes it possible to form MEEMSAL generations, some of which will be the future elites and decision-makers of our different nations, which in the long term, will create a healthy environment on a global scale. .展开更多
