Re: what that "drastic action" may be is unknown
Even a marble dropped from orbit can have one heck of an impact if it hits the ground...
But by and large it wouldn't.
Space rocks have to be a fair bit bigger than a marble if they would have to have a marble-sized remnant hitting the earth; most of it will burn up. If you start with a marble there may be several dust specs arriving at altitude zero, but I guess you' agree that their impact wouldn't be particularly impressive.
I guess that if you threw a marble out of the ISS its entry speed may be low enough that less of it will burn up compared to an honest marble-sized meteoroid before the remnant(s) hits the earth, but it will still be partly vapourised.
