正文(英文)	More than half of all of Earth’s ocean life died off 444 million years ago because of falling oxygen levels, a study has found. Experts believe that the ‘Late Ordovician’ mass extinction 450 million years ago was due to widespread ‘anoxia’, or oxygen depletion, over a three million year period.
