The burgeoning amount of carbon dioxide in oceans is affecting a lot more than coral reefs. It is also damaging marine life and, most ominously, threatening the future survival of marine populations.
New evidence suggests that we have already passed a dangerous threshold for the amount of carbon dioxide in the atmosphere and that the time for taking strong action is slipping away.
By taking bits of a single gene, scientists are using DNA barcoding to
identify new species. If a portable hand-held scanning device can be
developed, one ecologist says, it could “do for biodiversity what the
printing press did for literacy.”
