I think the ignorance lies in the belief that NASA, the guv-ment or any other entity is out there to protect the common person (read: you). All they want to do is protect their pocketbooks. The 1908 impact in Tunguska was how many years ago? And what has been done since? Goose-egg with the exception of the Saturday afternoon 3-D simulations on the Discovery Channel narrated by some academic hack in a cheap suit. 96 years since Tunguska and nothing but rants and raves. If you put a petition in front of me, I'll sign it. You wanna get organized, I'll lend a hand. But stop squawking.
I'd be more concerned with the caldera under Yellowstone National Park because it is 50,000 years overdue to erupt. Geyser activity was off the charts this summer/fall when I was there. But the media doesn't give it anywhere near the amount of ink as space debris because it is not as sexy. Hence, it won't sell. Hence, hence, $$$.
In the interim, you might want to take that duct tape and plastic that Ridge told you to buy and add a second layer. Because I know you bought some...
