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.

Half a billion eggs suspected of carrying salmonella have been recalled in what’s become the largest egg recall in U.S. history. And many people are wondering: How did this happen?

All this week we’re talking with our friends from Scientific American about endings: in nature, culture and science. For most of human history the clearest, most black and white ending in our lives was death. However, in recent decades, life support technology has made death a gray area, leading to right-to-life debates, as in the case of Terri Schiavo. But the question of when someone is dead becomes especially important when dealing with the process of organ donation.

We asked you, our listeners: If you are are an organ donor, what made you agree to it? If not, what's your reason against it? Let us know in the comments or call 877-8-MY-TAKE and we'll play the responses on the air.
