THE world’s oceans are becoming acidic at a faster rate than at any time in the past 65 million years, threatening marine life and food supplies, according to a study by British scientists.
Researchers from the University of Bristol found that when ocean acidification accelerated, it caused extinction at the bottom of the food chain.
The acidification was being caused by the amount of carbon dioxide coming from cars and factories, which was absorbed by the water, they said.
Since the industrial revolution, acidity in the seas has increased by 30pc. The last time such a fast change occurred was thought to be 65 million years ago, when a natural event caused ocean acidification.
