You stated that all of the above were going on all the time, forever.
Might wanna rein in your hyperbole a bit.
It is. Every second, no, but 100,000 times more than a man mowing his yard. Like I said, there's a known time limit on yard mowing, and you know you got a week or two break in between. Try having a Sunday grill out in town, and it will be barking dogs, rap music, and loud bike exhaust every few seconds.
