Is that scary enough for you?

Clarification, there is a lot of junk -- either approx. 300,000 tons of debris, or 3,000,000 tons of debris, can't rightly recall off-hand -- falling to Earth on an annual basis. That's a lot of crap, but it's mostly in the form of dust. There are, however, larger impacors that strike the oceans, generally undetected, and a few chunks (a fistful of scattered grams, possibly ounces, per bolide that would explode in the atmosphere due to heat exchange upon entry) that reach a solid surface, mainly around the poles.

Also, because a majority of the planet surface is unpopulated (regardless of the latest population explosions being reported), these measurable planet-strikers alight mainly in unpopulated regions.

Asteroids are tracked. Their orbital paths are known, being calculated by governments (note the pluralization) and private citizens (note the pluralization) alike, and with extreme accuracy reaching a few years into the future, which remain acceptibly accurate even beyond this, barring extreme perturbation. If there were any possibility of an asteroid strike in the near, or distant, future, the media would light up like a switchboard.

Remember switchboards?

Okay, so the media would light up like a Christmas tree.
