Saving lives

Ok, lemme think (keep in mind I stopped doing maths a year ago!)

First for DAIRY:

So, on average, a cow produces 8,375 litres of milk a year. Let's also say a cow needs to give birth to 1 calf a year (not sure if this '1 calf a year' is correct -- however, I shall base all the following on this )

On average, a human would consume maybe a litre of milk a week? So we can say 52 litres of milk a year.

So, 8375/ 52 = 161

This means it takes 161 years of living to save 1 bobby calf. Obviously we're not alive for that long, rather half of that. Therefore we can say we save 0.5 bobby calves in our lifetime.

NOW for EGGS:

The average battery hen lives for 1 year, laying 300 eggs in a lifetime. A person will probably only eat 4 eggs a week at MOST (15,600 eggs in a lifetime). It would therefore take the lives of approx 52 chickens to produce all these eggs.
________________________________________________________________________

GRAND TOTAL*:

0.5 bobby calves + 52 laying hens = 52.5

52.5 / 75 (avg life expectancy) = 0.7

According to my maths (which may be completely wrong!!!), the average vegan saves an extra 0.7 lives a year.

*I haven't included things like cheese, leather etc. Therefore, I think we can probably round it up to 1 whole life a year.

The average vegan saves 1 more life a year than a vegetarian.

God, I need something better to do on Saturdays.

Anyway, while it's nice to know vegans save an extra 1 life a year, veganism to me is much more of a statement than the number of lives saved; the statement that I'm choosing not to be a part of the exploitation of animals.

the omnis I know have about 3 litres of milk a week and some of them eat 2 eggs every day.
So if they convert they'd be saving more?
I think cows have a gestation of 9 months like us.

if you use my friends as the basis of how much dairy and eggs consumed by people:

a human would consume maybe a 3 litres of milk a week; So we can say 156 litres of milk a year.

So, 8375/ 156= 53.6

This means it takes 53.6 years of living to save 1 bobby calf. Therefore we can say they save approx. 1.5 bobbies in a lifetime.

NOW for EGGS:

The average battery hen lives for 1 year, laying 300 eggs in a lifetime. A person will about 12 eggs a week; 46,800 eggs in a lifetime (holy crap, their cholestrol is going to kill them). It would therefore take the lives of approx 156 chickens to produce all these eggs.
________________________________________________________________________

GRAND TOTAL*:

1.5 bobby calves + 156 laying hens = 157.5

157.5 / 75 (avg life expectancy) = 2.1 lives a year

*I haven't included things like cheese, leather, additives, honey etc.

But you're right not that it matters as much. Being a vegan is a statement. I was interested to know how many more lives with the data from my friends eating habits.

I think there would be a whole lot of bees dying from their honey being taken too.

That is some serious maths right there Matt.Y
I thought vegans saved more lives per year but then again even if its only one then thats like 80 in your lifetime. Pretty awesome!

That made my head hurt.. O.o

thank you for the maths!

but myself and my family as well as friends i know all used to (or still do) drunk/drink more than 1 litre a week, i used to drink heaps..
I think it would be more than one life a year if we include everything, and i guess its all down to the individual as well..

but yes i agree, its the statement, not the numbers.

Where the hell did you get these stats from!?

Also, it's not just death we ought to worry about.
There are convincing arguments that say there is more suffering in a carton of milk than in a plate of flesh.
