Captain Cook’s Introduced Goats and Pigs Impact Native Ecosystems in Hawaii and New Zealand
In the late 18th century, Captain James Cook introduced goats to Hawaii and pigs and goats to New Zealand as future food sources for sailors. Over time, these animals became feral and caused significant ecological damage by harming native plants and forests that evolved without such predators. Efforts like fencing, using collared goats in Hawaii, and pest removal on New Zealand's Motuara Island have helped control their populations and restore native ecosystems. These cases highlight the long-term environmental impacts of introduced species.
