Humans and falling asteroidslling asteroids

This is nothing particularly alarming. Millions of metoers enter the Earth's atmosphere every day, this one just happened to be a bit bigger than most, but still small nonetheless. If a civilisation-ending meteoroid or comet appeared on the scene, we'd know about it.

Hi guys!
A meteor with a diameter of 50 meters flew through the Russian sky today. And space agencies had not alerted people about the possibility of this event. A lot of people have been injured (not very seriously) by a blast wave from the meteor (not very seriously). But what would happen if there were a 500 meter diameter asteroid? Or a one kilometer diameter asteroid?  Are humankind's technologies advanced enough to prevent such a planetary catastrophe? So what do you think?

I think Russia just "dodged a bullet," but cosmic bullets have have hit the Earth in the past, and will probably hit us again.

I am sorry that people were injured, but glad to hear that the injuries were not very serious.
