All week long, in partnership with our friends at Scientific American, we’re talking about "the end" on The Takeaway. Whether it’s melting glaciers, the falling water table, or even how the world itself will end.

Yesterday we examined the stunning evidence of how Western civilization is changing and, in some cases, eliminating indigenous cultures. Half of the world’s 7,000 languages are endangered, and when language dies, whole cultures can disappear. Vital, ancient wisdom can be lost.

So we asked you: What traditions or wisdom do you think is worth saving? And what do you do to preserve them?

And we got a great deal of responses back from all of you.

Marco called in from Oklahoma to say:

"There's an American tradition that I miss and it's going away, and that is the American tradtion of a 'can do' attitude without the bragidociousness that we exhibit today. We've become a nation of whiners and braggers, yet we do less than we used to."
