Uncertain future of sustainable fisheries environment in eastern boundary upwelling zones under climate change

evidence

The four eastern boundary upwelling systems — California, Canary, Benguela and Humboldt — occupy about 1 per cent of the ocean surface and produce on the order of 20 per cent of the global fish catch. Read via search summary alongside an IUCN review chapter making the same statement; neither source was fetched, and the underlying fisheries accounting was not traced.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
