(AP Photo/Susan Walsh) The Associated PressWASHINGTON (AP) — Prince Charles is in Washington talking about environmentally friendly farming, and he says it's a change from giving royal wedding toasts.After greeting students at Georgetown University on Wednesday, Charles spoke passionately about organic and sustainable farming for almost an hour. He made only brief reference to the worldwide hubbub over his son Prince William's wedding to Kate Middleton last week. Charles called his remarks "a change from making embarrassing speeches about my eldest son during wedding receptions."In his speech, the Prince of Wales criticized government subsidies for large-scale agriculture, and also decried industrial pollution and global dependence on oil.Charles is scheduled to meet with President Barack Obama later Wednesday during his three-day visit to the United States.
