Sociolinguistics 9, Exercise 3: loss or natural process?

Position 1 (the Endangered language article): most linguists see loss as an
ethical and scientific problem, since future research will see only a fraction
of human linguistic diversity. The article adds that losing a language can
erode songs, myths, ecological knowledge, social cohesion and political
standing.

Position 2: some linguists, such as Peter Ladefoged and Salikoko Mufwene,
view language death as a natural process.

What the page cannot settle: the page reports the positions but does not
resolve them; whether a loss is "natural" or caused by political and economic
pressure (it lists repression and marginalization among causes) is a question
about the evidence in each case. It also gives only a wide estimate (50% to
90% by 2100), so how much will be lost is uncertain. How these two positions
should be weighed is a judgment, not something the sources decide.
