Prakash - that's shocking
Spana - the problem as I see it is that the economics of farming are twisted. Watching some farming videos, you could be forgiven thinking you were watching an episode of Top Gear. Huge combines, multiple tractor / trailer combinations servicing them etc.
Of course we can't go back to the horse for horsepower (or could we?) but our reliance on economies of scale and high oil use are dangerous in the longer term as oil is only going to get more expensive.
It's a sad fact that many (most?) of the people working on farms and in food processing are low-cost eastern Europeans. We Brits just won't pay enough for food to give a decent wage to the people who produce it.
On the other hand, we pay a packet to the banks to pay inflated property values. Our food is now a much smaller proportion of our income than it was 25 / 50 years ago but that 'saving' has been more than outweighed by the increased mortgage or rent.
How we put this situation right is beyond me. We've seen the effect of leaving it to the market with the banks but exactly how you change things to localise food production, get people to understand seasonal means no strawberries in January and pay for quality, I don't know.
Of course, there is another view - the demolition of large scale farms in Africa has resulted in massive drops in production. Countries like Zimbabwe and Nigeria were food exporters but now..
