I just watched ‘Andrew Marr’s Megacities’. Mr Marr said that megacities are the future and he obviously found them to be extremely exciting places. However, he did point out that they have huge food footprints. For example, London needs to produce food on an area that is equivalent in size to the whole of the UK. His solution was to grow food indoors, hydroponically – this is probably okay for vegetables but I think it would be difficult to produce wheat and beef (essential for the fast-food burger) with such a system.…
A report commissioned by the Greater London Authority claims that Londoners eat a staggering eight billion meals a year and produce nearly 19 million tonnes of greenhouse gas emissions.
Can this really be our future?
