how can I know where you food comes from,
I don't know, but your statement above indicated that you do.
You lied, again.
How can I know where your food comes from
You should have thought of that before you blurted out "most of your
food ingredients are actually imported from water deficient
countries
...".
good, so where do your food ingredients come from then?
For argument's sake, and because it involves everyone, let's
say that my "food ingredients" come from all over the world.
Now tell us what should be avoided (support with evidence).
simple
Don't eat imported food.
That rules out livestock products then, as you use imported feed.
yes, but I admit it
Wow.
.. and the UK is rapidly becoming a water-deficient country too..
not for agriculture. May have to ration domestic use in the SE
Crops aren't being irrigated there yet?
Stick with UK seasonal vegetables
I'd like to see evidence of vegetables causing water depletion.
Simple.
What is the water content of most vegetables?
If it's that simple you should be able to provide evidence
that vegetable production is causing water shortages. In
fact it is the extensive deforestation to create pasture and
feedcrops that has caused aridization; now compounded
by the need to irrigate to keep up your omnivorous habit.
'(i) Micro-climate: Deforestation of TRF leads to drastic
changes in microclimate (Lal and Cummings, 1979), as
outlined in Fig. 6. In general, deforestation eliminates the
buffering effect of vegetation cover and accentuates the
extremes. Fluctuations in micro-climatic parameters are
greatly enhanced (e.g., relative humidity, maximum and
minimum temperatures for soil and air). Deforestation
decreases rainfall effectiveness and increases aridization
of the climate. Forest removal increases the magnitude
and intensity of net radiation reaching the soil surface.
Ghuman and Lal (1987) observed that in south central
Nigeria, on average, 10.5 and ll.5 MJ/m2/day of insolation
were received on a cleared site compared to 0.4 and 0.3
MJ/m2/day in the forest during the dry seasons of 1984
and 1985, respectively. There was no appreciable
difference in solar radiation received under forest during
the rainy (May) and dry (December) seasons (Table 8).
Vegetation removal also increases wind velocity (Table 8).
Deforestation decreases the maximum relative humidity,
especially during mid-day. There is also a corresponding
increase in air temperature and evaporation rate. Perhaps
the most drastic effect of deforestation is on soil
temperature. The maximum soil temperature at I to 5 cm
depth can be 5° to 20°C higher on cleared land on a sunny
day compared with land under TRF cover. Because of
high soil evaporation, the soil moisture content of the
surface layer is also lower in cleared than in forested soil
(Fig. 7).

After all you are a vegetarian
So what. We all eat (-need- to eat, for survival and good health)
vegetables, fruits, nuts, legumes and so on. Try living without.
then why do you buy imported vegetables?
People buy imported vegetables because a wide variety
of fresh produce is important to maintain good health.
Why won't you comment on the inefficient overuse of water
for the livestock industry, jim? You are too embarassed to?
no, we use all that water that falls on grass or would otherwise go to waste
You're forgetting about all that imported feed.
don't need to, you rant on about it all the time
You do need to, as you are trying to shift the blame onto others.
but it has taken over a week to admit that you are every bit as guilty
I have not. There's no way I could be. It is inefficient unsustainable
consumption for and by the livestock industry that is causing global
water shortages, - requiring 15 to 22 times the water for the same
amount, and at about 40 percent of global agricultural output, that's
nearly twice as much as would be used for plant foods alone - and
~you~ try to blame foods being produced for human beings directly.
Shame on you, webster. Maybe one day you'll find a backbone.
I'm not the one who took over a week to admit what she eats
Stop lying already, webster. I told you way back what I eat.
and still cannot
conceed that by importing vegetables she is importing water
You still can't provide evidence of vegetables causing drought.
Also if water is such a big deal, I'd point out that the amount used in
agriculture in the UK is less than is used by the domestic population
What percentage? A link with that would be helpful.
How many liters of water do bovines consume per day?
