How Much Of The Ocean Is Fished?

Seen in → No.50

This is a perfect example of what I’m saying in the intro; what do we measure and how do we interpret the numbers?

This seems like a simple matter of scale. If you look at the world at different resolutions, you’ll see different pictures. So the question becomes: Which is the right resolution to use? […]

These same contentions also apply when comparing land and sea. In their original study, the GFW claimed that fishing affects 200 million square kilometers of ocean, which is four times greater than the 50 million square kilometers of land that’s affected by agriculture. But Amoroso’s team notes that the latter figure comes from studies that use a much tighter grid. If you analyze land and sea at the same resolution, it’s agriculture that outmatches fishing by a factor of four.
