Scientific possibilities often raise moral dilemmas. Take "roborats" for example. It seems we know how to put an electrode in a rat's brain and then, using remote control, employ it in minefield clearance. We have the technology, but should we use it?

The BBC's new 10-part spectacular on The Life of Mammals devotes a whole programme to rodents. On page 24, David Attenborough reflects on his animal ventures: "The environment wasn't an issue in the 1950s... natural history programmes have changed perceptions."
