Heavenly bodies keep releasing large lumps of rock that threaten the Earth with extinction, the Earth goes on spinning around without retaliating.
Maybe we can send the other planets a message in kind by sending one part of the Earth that is not needed as a meteorite.
I have not read anything about meteorites released by the Earth. Where could they be now? Do they possess any life forms? Besides, which part of the Earth can we use as the scapegoat?
The dense core and inner mass of the the planet results in a significant gravitation attraction toward the earths core which keeps material positioned about the core. Try dropping a rock and get a demonstration of the effect of gravitation in action.
Earth doesn’t release large chunks into space because its strong gravity holds everything tightly; it takes immense energy to overcome escape velocity (11.2 km/s). Only extremely powerful asteroid impacts might eject small fragments, and even then, it's rare. A few meteorites found on Earth may have once been Earth rocks launched into space and returned. These fragments could, in theory, carry life, but none has been confirmed. So, Earth isn't in the habit of "retaliating", it prefers to stay whole.
Well, there is an article published in 2019 reporting a putative Earth's chunk found on the Moon. Very interesting feature.
You can find it here: Article Terrestrial-like zircon in a clast from an Apollo 14 breccia
