UNESCO is the United Nations agency that is responsible for coordinating efforts to preserve endangered languages.

UNESCO's Endangered Languages Programme aims to document and preserve endangered languages, promote their use in education, and support their revitalization.

UNESCO estimates that more than 5,000 languages are endangered.

Globalization, economic development, and climate change are all factors that can contribute to language endangerment.

Language loss can lead to the loss of cultural diversity, traditional knowledge, and biodiversity.

International organizations can help preserve endangered languages by documenting and recording them, supporting language revitalization projects, and promoting the use of endangered languages in education.

International organizations face a number of challenges in their efforts to preserve endangered languages, including lack of funding, lack of political will, and lack of community support.

International organizations have had some success in their efforts to preserve endangered languages, including the revitalization of the Hawaiian language, the documentation of the Ainu language, and the promotion of the use of the Maori language in education.

Individuals can help preserve endangered languages by learning an endangered language, supporting organizations that are working to preserve endangered languages, and advocating for the use of endangered languages in education.

Preserving endangered languages is important for maintaining cultural diversity, protecting traditional knowledge, and promoting sustainable development.
