The food pyramid is very complicated. It doesn't give you as much info in a quick glance as the plate does.

We should also challenge this country to come up with strategies and technologies that allow us to produce nuclear energy without necessarily producing a byproduct that can be converted to something far more dangerous. I believe that can be done. It may not be done tomorrow, but it clearly needs to be worked on.

I can't give you a specific number today, in large part because the analysis upon which we would make that determination has not been completed. . . . I think it is fair to say there may be additional costs associated with a farming operation, but it is very difficult to quantify.

To help producers serve larger institutional customers like schools and hospitals, USDA has helped fund new regional infrastructure like cold storage warehouses, commercial kitchens and local slaughter facilities.

I think the Iraqis themselves will have to make a determination as to what type of government they ultimately come up with and what kind of nation they ultimately come up with. But they can continually use America's troops presence. The problem is not going to change until they are confronted with the reality that they have to make decisions and they have to make them themselves. They have to decide whether they want a country, whether they're willing to put their lives on the line and sacrifice for a national interest as opposed to a regional or sectarian interest.

Over the past two years, the Obama Administration and USDA have worked to build a foundation for sustainable economic growth in rural America. At the center of our vision is an effort to increase domestic production and use of renewable energy.
