On a recent visit to remote Heard Island, located 2,500 nautical miles [4,600 km] southwest of Australia, scientists discovered dramatic changes in local plant and animal populations.
Hiljuti märkasid teadlased Austraaliast 4600 kilomeetri kaugusel edelas asuval Heardi saarel suuri muudatusi kohalikes taime - ja loomapopulatsioonides.
