Klein asserts, "It is more energy efficient to grow grain and feed it to people than it is to grow grain and turn it into feed that we give to calves until they become adults that we then slaughter to feed to people."

What about the idiocy of growing grain to fuel cars?

He covers it! Read the article.
“If you really want to help people, stop wasting corn on ethanol and soybean oil in biodiesel. We’ll need to double the world’s output of food and feed in the next 40 years just to meet the food needs of 9 billion people and their pets. Biofuels are a trivial waste of good land.”

Why do we grow so much corn in the first place? Because the government subsidizes corn production and places tariffs on foreign alternatives.

That's why there's so much darn corn syrup in everything. That's why we burn corn for fuel. That's why we feed so much corn to cattle.
