1 . Macquarie Island is a tiny island that’s part of Australia. It’s about halfway between New Zealand and Antarctica. The island’s been made a world heritage area because it’s so untouched, but this unique environment is under threat from some unwanted visitors.
It all started when seal hunters came to the island in the early 1800s. They brought rabbits with them as a source of food for the journey, and also on board the ships were rats and mice, which made their way onto the island too. They’re being blamed for destroying the homes of marine birds, causing soil loss and ripping up plant cover, as these before-and-after photos show.
So what’s being done about the problem? It starts with a team of helicopters that fly across the island carrying these giant containers. Inside them are poisoned pellets (有毒饲料) which are dropped and spread across the island. For any rabbits that survived the baiting (诱饵) , there’s a plan B. This special team of dogs is being put through a final training. It’ll be their job to track down any remaining rabbits. They have to also learn to behave around the island’s native wildlife. The dogs could be here for years or until the task is complete. The dogs don’t actually kill the rabbits. They find them, then the hunters decide to either catch the rabbits or shoot them.
But the program has received a bit of criticism. Some people argue 25 million dollars is a lot of money to be spending on wiping out rabbits and rodents (啮齿目动物), and in the process, some native birds will be killed because of the baiting.
The reality is the problem isn’t going to be solved overnight. The people running the program say that even if one pair of rabbits is left alive, the whole task will be seen as a failure, which means these guys could be here for a long time, trying to ensure that this precious island remains protected from pests.
