There's a nice article on organic farming over at New Scientist.
I watched HP5 a couple of days ago. It was nice - dark and moody. The essentials of the book were in it (as far as I could remember), but - of course - a lot was cut, so the film really could have been longer. Despite the 140 minutes it seemed quite short and a little too fast-paced. I don't think cutting Daniel Ratcliffe's hair was a good decision aesthetically and Sirius again looked too elegant and handsome. I'm also not sure if people who haven't read the book understand all that is going on in the film (Tonks' red hair wasn't explained at all, also pretty much her whole appearance; same with Kreacher). Still, as someone who has read the book and who watched the film for a nice visual reminiscence of a known story, it was good and enjoyable. The film has some very amiable characters who partly don't get enough screen time (Tonks, for instance). And some who do get their due screen time - I was looking forward to every appearance of Luna Lovegood and I still love Katie Leung's (Cho Cang) accent. All in all recommendable, even if you don't know the book.
Hm, I do wonder if it's common for British girls to yell "cute" and "awww" whenever a teenage character appears and does something "cute" (I admit, Ron had a nice hero-scene when he defended Harry, but it's nothing that I find culturally justifyable to go vocal about).
Started as a sketch to get into the flow, thus the boring content:
