"The Sustainable Prince"

"Less than a week after the wedding of his son William to Kate Middleton, Prince Charles was in Washington on Wednesday to, among other things, speak at a Georgetown University conference on the future of food and sustainable agriculture, a pet issue of his for nearly 30 years. The heir to the British throne gave an earnest and statistics-heavy address touching on such staples of the natural food movement as the virtues of composting and the need to maintain biodiversity.

But first he expressed his gratitude for having been invited to speak at Georgetown, where he last appeared in 2005 to deliver remarks on faith and social responsibility."
