Illiteracy is understood as the inability of a human being to perform the basic operations of reading and writing. Illiteracy appears as a result of a lack of education and although the percentage of the world population still immersed in such conditions is infinitely lower than at other times in history, there are still numerous societies and communities that have a large part of illiterates in their population. .
Illiteracy is one of the main problems and debts of Humanity since those people considered illiterate are not by their own choice but because of the existence of high levels of poverty, misery and lack of educational opportunities in the environment in which they find themselves inserted. So much so that illiteracy rates are clearly visible in developing or Third World countries, countries in which educational systems are deficient or are not a priority at all.
In this sense, the African continent, as well as some countries in Asia and Central America, are the regions of the planet with the highest percentages on the planet. They are followed by some countries in Latin America and Asia, while in industrialized or First World countries such as Europe, North America and Australia such percentages are very small.
UNESCO (United Nations Educational, Scientific and Cultural Organization) is the body responsible for carrying out important literacy campaigns and processes in different regions of the planet, respecting the cultural differences of each country or community. One of its main objectives is to stimulate elementary education by considering it the basis for the acquisition of the first knowledge and to ensure that each individual can develop fully throughout his life. The tasks of this body are basically the contribution of funds for the construction of schools, the establishment of new technologies, the creation of favorable environments for education and the maintenance of the basic structural conditions for schooling in all its forms.
