Ocean life threatened by industrial emissions

The Earth's oceans are acidifying at the fastest rate in 300 million years, threatening marine life
Ocean marine life is at unprecedented risk as our oceans are acidifying at the fastest rate in 300 million years, scientists say.

The rise in the ocean's water acidity comes as the seas absorb a quarter of carbon dioxide polluting the atmosphere, which in turn as increased by nearly a third over the past century.

Professor Andy Ridgwell, of Bristol University, is alarmed by the unprecedented rice in acidity levels.

"Current acidification is potentially unparalleled in the last 300 million years," he said.

Past instances of ocean acidification have been linked with mass extinctions of marine life.

Barbel Honisch, of Columbia University, wrote in Science journal: "If industrial carbon emissions continue at the current pace, we may lose coral reefs, oysters and salmon."

Researchers based in the United States, the United Kingdom, The Netherlands, Germany and Spain contributed to the study, which was funded by the U.S. National Science Foundation.
