Fascinating article. I had not realized that ethanol could have such an impact on world hunger. Makes me reconsider my preconceptions. That's what good journalism is all about.

An important story on a theme that is slowly becoming mainstream: the limited capacity of farming to produce both our food and our fuel. Lester Brown is more of a source than a journalist, so it is not surprising that many of the facts in this story are uncited. But I trust Brown, and he cites enough sources to render a credible opinion.

Excellent article indeed, coming from the president of the Earth Policy Institute. It clearly shows in a logical way the merge of food and energy industries and the consequences on world hunger. Most important, the author suggests sustainable energy alternatives, like wind farms to power electric cars on short distances and the raising of auto fuel-efficiency standards, in order to avoid a big problem with the world's food needs in the near future.

A valuable contribution to an increasingly important debate. Clear and authoritative. Would have liked to see responses included from bio-fuels proponents.
