I wonder how it affects the rotation of earth....because these 10^12 kilogramms (you wrote 1^12 but i guess you meant 10^12 right?), is being transported from here to there all over the world so the center of mass is changing all the time. I had to think of that, because i recently heard, that when its autumn in one part of the world and all the leaves fall down, that also changes the rotation (can anyone confirm that?).
what is also interesting is that mass of earth is 6*10^24 kilo. this means we eat almost half of earth's weight every year. maybe we have to recalculate your result there. but still funny thought somehow. lets just hope earth is still here in 2 years 😛

So I can't confirm that, sorry.

cow burps, producing methane, a greenhouse gas 20 times
more greenhousie than CO2. What about HUMAN burps?
and human farts. Surely 6 billion burping and farting humans
have to be taking a toll on the atmosphere.

Originally posted by sonhouseI don't think burps generate methane, not from cows, nor from people, perhaps from dragons.

On the other hand, farts produce methane. But this is so small amount that it doesn’t really matter. As my doctor said: "Fabian, don't be embarrassed, farts is only natural" and how could natural things hurt nature?
But again - perhaps it was just that who killed the dinosaurs 65 million years ago, they farted to much?

Originally posted by FabianFnasBut there is a lot more land in the Northern hemisphere than there is in the Southern hemisphere, so the effects on the Earth's rotation caused by the Northern hemisphere are not countered by the Southern hemisphere.

from digesting vegation. So maybe human vegans generate more
gas than we thought....

Well the leaves would have the same mass on the floor as on the tree so I don't see who this would effect it at all.
I don't think many of these effects would be anything compared to the tides think of the massive weight of all the water shifting around the globe.
Oh and methane can be produced by fermentation in anaerobic situations.

effects the earth, one factor in generating earthquakes:
The atmosphere. The actual weight and force of the air has been
proven to have an effect on generating earthquakes. Remember,
the continental crust is rather thin compared to the whole mass of
the earth and the atmosphere sloshes around considerably
and exerts a downward force at times, also at times a lesser force,
which is one element in the stirring up of continents. Just thin air
is more forceful than we once thought.

Originally posted by sonhouseOf course, this begs the question of how much crap we produce everyday. But I don't want to get my hands dirty with that one... 😞
So I go, assume one pound per day, conservative estimate I think.
so 6 billion pounds per day or times 365 which amounts to 2.2
TRILLION pounds per year. That doesn't even count beer.
So 2.2 Trillion pounds is 1 trillion KG, 1^12 Kilograms of food per year.
Thats a lotta enchaladas.
