Nothing worse than those in the public spotlight trying to get their fifteen minutes of fame:

Perhaps if they spent a little while researching the facts surrounding these very complicated issues instead of pounding the pavements they might direct their fire in another direction.
For example corn prices have shot up in the States partly due to the drought they are experiencing. What these poor children probably don't realise is that 40% of that corn goes into the little hole at the side of their cars to make them go whizz whizz in order to save the planet.
Not only that all that exercise they take requires them to eat a whole lot more than the average person.
Perhaps they need to look a little closer to home before trying to explain the complexities of this really important issue.
