NANFA-- another good reason for preventing extinction.

I don't if any one here follows astrobiology but a book that came out a
couple of years ago that makes the case for avoiding the extinction of
complex life more than a little stronger. The book is called "Rare Earth" the
central idea of this book is that complex life, that is life above the
bacteria level is likely to be rare if not non existent outside the earths
biosphere. That would mean that when a life form becomes extinct not only is
the loss just to our earth but to the entire universe as well. They make a
very good case that the earth or earth type planets with complex life may be
very rare due to very unusual circumstances that at least statistically would
seem to make Earth unique. The list is long so I won't go into it here but if
true ET just might not be out there after all or any animals, plants, or
bug-eyed monsters. Reading this book was a paradigm shift for me because I
have always believed that eventually planets with animals and plants not only
would be everywhere but must be. It's a great read.
