Which is NOT a factor indicated for the likely extinction of some languages?

While approximately 7,000 languages are spoken in the world today, only about half are expected to survive this century. A number of factors contribute to this loss: increasing globalization, which pushes countries and individuals to shift to national or international languages for economic reasons; lack of support for regional languages in educational systems and mass media; persecution of minority linguistic groups by governments and disruption of communities during war and emigration.
    It is difficult to predict the future for any particular language. While some minority languages will thrive for generations to come, many of the world’s languages are moving towards extinction within a generation.
    One stressor that may be the tipping point for some communities is climate change. Many small linguistic communities are located on islands and coastlines vulnerable to hurricanes and a rise in sea levels. Other communities are settled on lands where increases in temperature and fluctuations in precipitation can threaten traditional farming and fishing practices.
    These changes will force communities to relocate, creating climate change refugees. The resultant dispersal of people will lead to the splintering of linguistic communities and increased contact with other languages. These changes will place additional pressures on languages that are already struggling to survive.
    When a language is lost, the result can be a loss of identity, one that may impact the health and vitality of a community for generations to come. The importance of the connection between language and identity can be seen here in Canada.
    The loss of a language is also a loss of data needed to better understand human cognition, as happens when a language disappears before its structures and patterns have been documented. It is a loss of knowledge about the world as well, as when descriptive names for plants or practices—still unknown outside a local area—are forgotten.
