Food shortages

[bigpaul]

given our population levels in the UK we cannot feed all the people living here without levels, although we are 60% self sufficient in food as a nation most of that food requires fertilisers, pesticides and herbicides all of which are imported, as most agriculture(most but not all) is of the mono cropping type heavy in the use of such chemicals if we cannot import them commercial food growing in this country would stop.
if imports of oil also stopped that would be a double whammy.
