International Mother Lanugage Day is an initiative of Bangladesh. It falls every year on February 21. It was approved at the 1999 UNESCO General Conference and has been observed throughout the world since 2000.
Audrey Azoulay, Director-General of UNESCO, on the occasion of International Mother Language Day said, "The theme of the Day this year, "Fostering multilingualism for inclusion in education and society", thus encourages us to support multilingualism and the use of mother tongues, both at school and in everyday life. This is essential, because when 40% of the world's inhabitants do not have access to education in the language they speak or understand best, it hinders their learning, as well as their access to heritage and cultural expressions. This year, special attention is being paid to multilingual education from early childhood, so that for children, their mother tongue is always an asset."
UNESCO also mentions that linguistic diversity is increasingly threatened as more and more languages disappear. According to UNESCO, 40% of people in the planet don't have access to get education in their native or mother language.
UNESCO mentions, "Multilingual and multicultural societies exist through their languages which transmit and preserve traditional knowledge and cultures in a sustainable way."
"The theme of the 2021 International Mother Language Day, “Fostering multilingualism for inclusion in education and society,” recognizes that languages and multilingualism can advance inclusion, and the Sustainable Development Goals’ focus on leaving no one behind. UNESCO believes education, based on the first language or mother tongue, must begin from the early years as early childhood care and education is the foundation of learning," UNESCO website added on World Language Day 2021.
