Not Shark or Seal: Penguin's biggest predator on this island is a 20-gram animal and South Africa is now planning a 550-tonne poison solution

South Africa is preparing a large-scale operation to eliminate mice on Marion Island. Helicopters will drop 550 tons of poison bait across the island's landmass. This effort aims to protect vital seabird breeding grounds from rodent predation. A trial operation is scheduled for April and May 2027. The eradication is considered essential for the island's unique biodiversity.
