Rat eradication ship sets sail for South Georgia
A team sets out on Saturday on the final leg of a mission to eradicate rats from the island of South Georgia, with the aim of "reclaiming the island for its seabirds".
Their ship, loaded with three helicopters and almost 100 tonnes of poisoned rat bait, sets sail from the Falkland Islands.
The project has been under way for more than five years; this is the last of three bait-spreading stages, as Victoria Gill reports.
