New Zealand’s Prime Minister John Key on Monday announced a program to make the Pacific Ocean nation “predator free” by 2050, ridding its islands entirely of invasive species that are a threat to endemic birds and other native species. The project would be the first of its kind in the world. A press release from the ruling National Party, which Key leads, says the government will put almost $20 million a year of new money — on top of more than $40 million that already goes into pest control annually — into various projects targeted at wiping out three species: rats, stoats and possums. According to the Guardian, pest-control methods currently employed include trapping, ground baiting and hunting.
