Q.E.D.

I was only talking the other week about there being two sides to every coin, and now we have a case in point. Biofuels were not so long ago - and to a certain extent, still are - seen as one of the major answers to both the shortage of oil, and global warming. Lots of money has been ploughed into their development. Now we learn that devoting land to growing crops for biofuels has resulted in shortages in staples like cereals and sugar which has led to higher food prices . Can't win, you see!
