the anthropic principle doesn’t work, here, because not-all species become extinct during these events.

i actually favour the following particular hair-brained geo-forming project:
-> restore the Sahara desert to its former, lush savanna, by desalination and irrigation projects that use fusion energy.

Algae rule!
Actually, the anthropic principle always works. We just got lucky. In slightly different parallel universes, it didn’t work out so well.

The expression, btw, is actually “hare-brained”: http://www.phrases.org.uk/meanings/42400.html. :cheese:
