I'm a nut for dinosaurs. I am often asked why. It's not the animals themselves, though they are awesomely awesome. It's the idea that dinosaurs are our very own extraterrestrials: our own alien species. Our planet was their homeworld, and now they are no more.
At some point, it's likely another species will replace us on the Terra Homeworld. I don't find that depressing. It fills my imagination of what things will be like then in the same way I imagine, regarding dinosurs, what it their then was like.

Author Alan Weisman has published a book titled The World Without Us (NY: Thomas Dunne Books, 2007; ISBN: 978-0312427900). His website for the book has this description:
"In The World Without Us, Alan Weisman offers an utterly original approach to questions of humanity's impact on the planet: he asks us to envision our Earth, without us.In this far-reaching narrative, Weisman explains how our massive infrastructure would collapse and finally vanish without human presence; what of our everyday stuff may become immortalized as fossils; how copper pipes and wiring would be crushed into mere seams of reddish rock; why some of our earliest buildings might be the last architecture left; and how plastic, bronze sculpture, radio waves, and some man-made molecules may be our most lasting gifts to the universe."
