The International Day of Sign Languages is a once-in-a-lifetime opportunity to support and defend all deaf people and other sign language users’ linguistic identities and cultural diversity. The World Federation of the Deaf launched the Global Leaders Challenge in 2020. This challenge intends to encourage local, national, and global leaders to utilize sign languages in collaboration with national deaf associations and other deaf-led organizations in each country. There are roughly 72 million deaf people worldwide, according to the World Federation of the Deaf. They make up more than 80% of the world’s population and live in underdeveloped countries. They employ around 300 distinct sign languages collectively.
