020 - Fishing
In this video Paul Andersen explains how various techniques have been used for years to collect seafood. Commercial fishing has led to overfishing in certain areas and species due to the tragedy of the commons. An explanation of aquaculture and sustainable fish yield is also included.

i havent been eating any seafood in the past couple months and i feel like it's out of guilt, or maybe its one of those "if i dont eat any seafood then i wont think about how scary it would be to destroy ecosystems like that". anyway, great video

Anyone here cares to explain the sustainable field at 4:26? I don't understand why "if fishers are placed on the red line" the population stays the same? Isn't the population supposed to decline if fishers reach that cap? Why is the sustainable field shaped as an arc?
@shayla1416
@shayla1416 5 лет назад
The curve is showing how much you can catch while not depleting the resource (that’s the part under the arc). So basically in order to not have a species go extinct the fishers can only catch the amount of the arc line or under
