"must admit wasn't impressed by presenter" - Martha Kearney is a very good journalist, and also a beekeeper, she's presented the Today programme and has regularly appeared on Newsnight - she's certainly no fool!
As for the programme, it's "old news" by now - I saw it's first screening, and like many was frankly horrified by many aspects of the way bees are kept in the US, and the shots of the vast monocultures underline just how badly mainstream "Big Ag" agriculture has "got it wrong", I think it was a fair appraisal of things as they were then - if nothing else I think it trumpets that there has got to be a "better way" for farming in general, it's now become an overused saying, but I still think it very true - bees are the canaries in our coalmine. When they start dying, and we can't work out why (because there are so many potential things that could be conspiring to cause those problems), then we need to look very long and hard at the way we produce our food, and how we treat the environment........
