More On Planetary Defense

A long term vision for humanity and its offspring must include the idea of stewardship, of gardening, nurturing and protecting the worlds we inhabit.

In 2004, before becoming NASA administrator, Mike Griffin had some outstanding words on the subject, and what needs to be done:
"Mister Chairman and members of the subcommittee, thank you for giving me this opportunity to comment on the greatest natural threat to the long-term survivability of mankind, an asteroid impact with the Earth. "
