Your article makes a great point, and one which was argued in The Future of Food, where they looked at lettuces produced in India and exported to the UK. Each lettuce used 15 litres of clean water to produce!! (I was astounded by this). When exported, it still contained a huge amount of fresh water in it (by it’s very nature). The interviewee (a professor from an Indian University) suggested that whilst Indian was suffering from one of the worst droughts on record, this was being caused by European economies importing their fresh water and in turn export drought!

And then there was the amount of oil used to produce the food (in the forms of automated machinery, production of packaging, transportation), and the effect this has on the environment.

It is a scary thought! The documentary then touched on “food wars”. This is not in the Western public domain yet. Perhaps it will never be allowed to.

At a time when the US is also suffering some of it’s worst droughts on record, and it’s reservoirs are starting to run dry, the subject of allocation of scarce resources needs to be addressed urgently.
