Fortunately, there are others like me out there. According to today's New Scientist article UN urged to coordinate killer asteroid defences, the Association of Space Explorers is concerned too. After two long years, during which an asteroid might have hit Earth on any day, they've released a report noting that we have the technology to save the world, we just don't have the agency set up to do so.
They're asking the United Nations to form a new NEO Threat Oversight group, where NEO stands for Near-Earth Object, to advise the Security Council on the threat. Should the group find an asteroid impact is imminent, presumably steps could be taken to try to deflect the asteroid and to evacuate cities, just in case.
Don't forget that this year, we noted the 100th anniversary of the Tunguska Event, which thankfully took place in isolated Siberia. Had the Event occurred over a populated city, hundreds of thousands of people (possibly even millions) might have died.
I urge all of you to contact your elected representatives and let them know how seriously you do take this threat. Sure, there are many other crises that are occupying the national and world psyche at the moment, but as Rabbi Hillel said, "If not now, when?"
