....no, you are assuming that the source I used only counted farmland and did not consider cattle. As for ratio's, for one thing, 2 cows per human... I am pretty sure we don't have that today... for another, the space required for a cow and the space required for a human are very very different. On top of that, you are assuming that the only meat anyone ever eats is Cow... ignoring fish, shellfish, sheep, goats, pigs, and various other meat sources (wich also vary based on location). Also, you are assuming a HUGELY disproportionate disparity in tech levels between those used for agriculture and those used for what we see in game.
as for eezo lightening the ship enabling fuel efficiency... maybe, but also probably NOT, remember, GETTING to FTL requires CONSTANT thrust, and then arriving in one piece ALSO requires constant thrust. On top of that consider the limitations of organics when it comes to thrust. Too much and everyone dies. I don't think we hear anything about inertial compensators... do we? if we do, then maybe it doesn't matter and they can ACTUALLY pull the stunts we see in cutscenes... despite, you know, every single piece of lore saying no...
EDIT: oh also, most cattle food can be provided by the same bits of land that feed humans, Hay is literally wheat stalks.
We have enough cattle to provide red meat for 8 to 9 billion humans nowadays and only recently they realised how unsustainable it is for higher populations.
Last time I checked, there was only 7 billion people on the planet, so I assumed that there was always enough cows around to consistently provide everyone on tbe planet with a moderate amount of meat and not suffer from a declining population, ergo I made the comment of having two cows- one to grow up, give birth raise the young one, get butchered...repeat...
Relying on white meat also causes several problems, mainly the possibilty of rendering fish species extinct, we came close to it a couple of times already.
Also a drawback of relying on fish is smaller busts and hips in women, the average bust and hip size in Japan has in fact increased since Japan has been shipping in red meat from other countries.
The only possible way to not to have cattle is to somehow physically and mentally control every persons eating habits.
The food industry expects you to want red meat at least once in your life, thus you would expect them to deliver, which in turn means they have to 'set aside' at least one cow just in case.
They also try to do it for everything else as well and all stacks up.
ME does in fact have interia dampeners, but they are connected to the eezo core, which means that the only time that they are fully working is at FTL, instead of the eezo core being used to generate shields and enable mass lightening of mass driver slugs.
They switch off artificial gravity when in combat to increase combat time as it lowers heat production, this causes them to have problems pulling off insanely high G turns as the people inside are reliant on the interia compensors to avoid going squish.
Also about ME FTL drive: on average it does fifteen lightyears a day at ten thousand times the speed of light.
The whole of 'constant thrust to speed up and constant thrust to slow down' would be closer to 'alright, lets go over here....wait! Stop! I want to get off here!'
Fuel economy gets weird at FTL, let me put it this way, lets say you cranked up your FTL drive up to ten thousand times the speed of light and you wanted to travel one light second which is around two hundred thousand > three hundred thousand kilometers...
At ten thousand times the speed of light, you would cross that distance in a tenthousandth of a second.
When you hit that kind of speed, braking becomes more of a concern rather than acceleration.
What does not help is the fact that bioware does not give a clear answer over how they came to that average, nor what kind of average.
But it is generally assumed that ion thruster based FTL is the worse due to having lower acceleration ability compared to fusion.
In all likelyhood it goes like this:
Ion thruster: Terribly inefficient, offset by really cheap fuel and used for automated cargo transports, these have the lowest FTL range due to low impulse engines not providing rapid acceleration to take advantage of the Mass effect.
Fusion torch: Efficient engine with high impulse, suitable for civilian craft and cruising military craft, relatively cheap fuel and easily maintained, just do not expect it to get you there instantly.
Anti matter to matter drive: Extremely efficient engine due to energy release from proton to anti proton collision. Makes the fusion torch look like a fire cracker, makes your ship go up like one too, if the containment fails. A shame that even a few nano grams costs thousands/millions of credits, which means only government sponsered ships can afford it.
Fuel really only appeared in the last two games, but considering that a ship the size of the SR 2 which was rated at around two hundred meters long could travel from at least one system to the next one before running out of fuel is in fact proof that eezo does help with fuel economy by boosting your overall acceleration.
In RL, just to cross over to our closet neighbouring star requires a vast amount of normal fusion fuel.....look up the 'daedalus project' if your interested.
What you have to remember about spacecraft is that their fuel economy is dictated by their overall mass, the more mass they have, the more fuel they have to burn, the more fuel they have, the more mass they have.
This is what every rocket engineer has to take into account when building a rocket.
Now, what do you think happens when eezo lowers a ship to mere micrograms or so?
That paradox goes out the window as all that matters is the size of drive core.
It allows for rapid acceleration far beyond what common sense would dictate, as you now have a ship that is more than a hundred times lighter than its supposed to be.
The mass lightening also applies to its stored fuel and its engine block.
If we were to use 'divide by a hundred' as a basis for mass lightening, then a properly built to fit fusion torch which would have the maximum output of 4Gs acceleration per second, would in fact be generating 400Gs of acceleration, as the ship its propelling now weighs a hundred times than its supposed to.
.....If I remember rightly, UberJJK had actually calced the overall difference in acceleration inside a FTL grade field and worked out that with AMM drive you could get to FTL within a few seconds, so you are not actually using up a lot of fuel.
For some reason Bioware ignores the fact that hand eye coordination caps out at around Mach Four and has organic pilots for their ships, which is ridiculous to consider in space combat in RL even without eezo letting you pull off more than 8G turns and acceleration.
Cows prefer grass and weeds over hay, they do not need drink water, but rather get it from digesting grass.
And yes, I did in fact take things like crop rotation into account, it still worked out the same, as cows would not be kept in the same field as crops that are currently being grown for humans.
Not to mention that in ME, 'genetic purity' of Earths ecosystem is also a big deal, they put laws in place in regards to modifying animals and plants in order to avoid alien hybrid animals and plantlife taking over Earths ecosystem, so its likely that Genetically Modified crops and such either do not exist, exist in small amounts or 'shunned'.
So...yeah, I do in fact expect difference between ME agricultural technology and technology from other branches.
