Fishing reduces carbon sequestration in the ocean, researchers report.
A fish that dies naturally in the ocean sinks to the depths, taking with it all the carbon it contains. Yet, when a fish is caught, most of this carbon is released into the atmosphere as CO2.
The researchers estimate that because of this overlooked phenomenon, carbon emissions from fishing are actually 25% higher than what, until now, was considered to come from fuel consumption alone.
What’s more, part of the carbon extracted from the oceans is in areas where fishing is not economically profitable in the absence of…
