Do you think that you could live on 7 pounds of various plant
foods per day? I know I could. Maybe you need to figure out for yourself. So you could go into a supermarket
and weigh seven pounds of produce on a scale there. Then you will know how much it is. It's
probably more than you think. Remember that if you include denser food like wheat berries (for your
homemade bread) a handful of wheat would be enough for a couple pieces of bread. Anyway seven
pounds is pretty close to what you can/might eat. I don't want to spend a lot of time figuring this out
for you but I think you will see that it's pretty close to what you might really eat.

So how much garden space would you NEED to GROW 7 pounds per day? The answer: about one quarter of an acre.
Really? You may ask. Yes really. You can do the math yourself or continue reading this page.

The statistical information listed In the tables below represent a crop-by-crop
average yield of 47 foods (in pounds per acre), according to two different sources. If we
calculate the average yield for all of these crops we find it to be 10,642 pounds per
* one acre* of land. Therefore, the yield for 1/4 acre is 1/4 of that,
or 2660 pounds.

If you grew *equal* amounts of all these crops (except rice -- I
*excluded* rice because it is so *unusually* high-yielding, and it takes *
lots** of water* to grow rice) on 1/4 acre of land, how many pounds of food
per day does that average out to be, in the course of one year, if you had *one* harvest
season per year?

** 2660 lbs./year **** = 7.3 pounds of food per day for one person.
365 days/year**

Do the crop yield figures (shown below) seem a little bit too high for you? Do
you really think that you could get, for example, 19,400 pounds of carrots out of only __one__
acre of land? One acre of land is 43,560 square feet, according to Random House Dictionary. If
that was a *square* piece of land, that would be **208.7** feet long on each
side of that square. (The "square root" of 43,560 is 208.7) If you produced 19,400 pounds of
carrots out of 43,560 square feet of land, that would be less than 1/2 pound per __one__
square foot of land:

__ 19,400 lbs. per one acre __
= .445 pounds per ONE square foot of land.

43,560 square feet per one acre

If you went into a supermarket to the bulk produce section, and weighted some
carrots on the scale, you would see that a half pound of carrots is a small handful of carrots.
Can you visualize this half-pound of carrots in a square piece of ground that is one foot long on
each side?* It appears to be reasonable to me!*

You could do similar calculations for the other crop yield figures below, but
you would find similar results: the numbers are quite realistic. Check it out for yourself, though.
Notice too, that CARROTS are one of the *higher *yielding crops. Therefore, MOST of the
other figures are even* MORE reasonable* than __carrots__!
