10. Should minority languages be saved from extinction?

I watched "Tears of the Antarctic" which is documentary. It is about how many creatures in Antarctic are suffering due to many reasons. This documentary doesn't relate with any language. However, there are same reasons that both languages and creatures in Antarctic have to be saved from extinction. First, there are many thing to learn form both languages and creature; how they occurred, and why they react or followed certain rules. Second both of them are our heritage which we could save for our descendant. the documentary that I watched doen't related with language but there were same reasons that support why people should save those from extinction
