‘Alien species threat to Antarctic environment’
Ecosystems in the Antarctic and sub-Antarctic islands are being irreversibly changed by alien plant and animal species introduced through human contact, a leading Antarctic researcher warned Tuesday.
British Antarctic Survey researcher professor Pete Convey, a visiting academic at New Zealand’s University of Canterbury, said the frozen continent had been protected from human contact until about 100 years ago, when humans deliberately and accidentally began introducing new organisms, Xinhua reported.
