......The report, produced by Nef and the Open University's geography department, uses a number of examples that it says illustrate how resources are being wasted, including:
In 2004, the UK exported 1,500 tonnes of fresh potatoes to Germany, and imported 1,500 tonnes of the same product from the same country
Imported 465 tonnes of gingerbread, but exported 460 tonnes of the same produce
Sent 10,200 tonnes of milk and cream to France, yet imported 9,900 tonnes of the dairy goods from France.......
I'm sure there must be valid reasons for the above
