DID YOU WATCH ‘HARMONY,’ AN NBC SPECIAL that aired November 19? I just did (thank you, streaming technology) and wanted to say that it’s a must. Prince Charles, whom the British tabloids dubbed the “tree-hugging prince” when he began talking about threats to the environment in the 1980s, is the principal narrator, threading together an impressive range of interviews from farmers, scientists, environmentalists and more. You can watch it here.
