My grumble with the show was when he got to GM foods. Much like most people (I imagine) I know little about the subject and they came across as very dismissive of people's mistrust.
He seemed to imply that people are scared/wary of them because of the negative portrayal of science as a whole and gave the nuclear bomb as an example.
Surely more pertinent examples are;
- The many poorly reported false health scares (e.g. Red meat is good for you AND gives you cancer depending on what day you pick up the paper)
- Vaccination scares (e.g. MMR)
- Drugs we've been told are safe but turn out not to be (e.g. Thalidomide)
To say "All we've done is make a potato plant that's resistant to blight, why wouldn't you want that?" is all well and good, but until it's 100% certain that there are no unforeseen circumstances that can propagate from that it seems sensible to be cautious... If that point has already been reached then that message needs conveying to the public as a whole.
