Islands, making up just 3 percent of Earth's landmass, harbor more than half of its endangered species. These fragile ecosystems, home to unique species that evolved in peaceful isolation, have been catastrophically disrupted by mainland predators-rats, cats, goats, and pigs ferried by humans to islands around the globe. To save these endangered islanders, academic ecologists have teamed up with professional hunters and semiretired poachers in a radical act of conservation now bent on annihilating the invaders. Sharpshooters are sniping at goat herds from helicopters. Biological SWAT teams are blanketing mountainous isles with rat poison.
