US oyster trade choked by rising CO2 levels

High water acidity due to higher carbon dioxide stunts oyster growth, hurting multi-billion dollar industry.

    The US secretary of state, John Kerry, has called for a global strategy to protect oceans from the effects of climate change. 

    The effects can already be seen in the oyster industry in the Pacific northwest region of the US.

    Oysters are unable to form shells due to high acidity caused by rising levels of C02.
