There was a teeny squawk on Twitter today when Tim Lang shared a graph of how the global harvest of cereals is divided up.

This is the graph he showed:

Graph of cereal use totals

My old mucker Luigi was quick to point out that the same graph could be expressed as percentages of the total yield, and that shows a very different picture.

Graph of cereal use percentages

The actual numbers:

1961: feed 36.86% Food 50.07%. 2013: feed 37.77% food 44.49%. Industrial uses climbs from 1.22% to 10.15%.

Feeding animals cereals that humans could eat is a problem, I agree, but in percentage terms, the growth of cereals as an industrial feedstock -- biofuels, presumably -- is far more worrying.
