The world is fine. We don't have to save the world. The world is big enough to look after itself.
- Douglas Adams, 2001.
If it ends up meaning that we go extinct like so many other species already have then other species will fill the space we live. The world is fine. So it goes.
Also, stick technology!
A long TED video (almost 1.5 hours) but well worth a watch:
"Douglas Adams: Parrots, the universe and everything" at TED and alternatively on YouTube.
