The world reached peak fish catch in the mid-90s. [1] And we now eat more grown fish than caught fish. The problem is that with increased acidity in the oceans, as part of the ocean absorbing mor CO2, we get less algae and eventually less fish. [2] But, yeah, let’s keep fishing until the stocks collapse. [3] They take a very very long time to recover.
