The usual phantasm about self sufficiency in food.
Agriculture uses vast amounts of water – 20,000 litres goes to produce just one kilogram of beef, including growing feed, watering the cattle and processing the meat – which will get much scarcer as populations and demands grow.
So, less meat and dairy then.
That will have to mean taking more care of the soil, the very foundation of farming; about half of our arable land is thought to be at risk of erosion, with intensive farming the main culprit. It will involve conserving water and fuel, and almost certainly increasing organic agriculture as artificial fertilisers and pesticides become scarcer and costlier.
Oh, so we need more meat and dairy to produce the organic fertiliser then (it being, after all, cow shit)?
You can\’t have it both ways now, can you?
Plus of course the point that fertiliser comes from natural gasa, not oil, and through frakking we\’ve just found anpothjer huge source of natural gas.
Oh, and of course, no till agriculture is the best way to build up the soil and you can\’t do that with organic farming. You\’ve got to use your herbicides and pesticides you see. Which implies, although doesn\’t insist upon, GM, which is also incompatible with organic farming.
It\’s the usual nonsense: something needs to be done so let\’s do this even whin \”this\” is entirely incompatible with what needs to be done.
And of course the truth is that we don\’t need to be self sufficient anyway, any more than France needs to be self sufficient in jet engines (which we make for them) or aircraft wings (ditto).
