A cross-posting from my Passed the Point of No Return blog.
Back in 1983-4 I had a lecturer on my undergraduate degree course from a wonderful lecturer called Alan Pitkethly. He is fondly remembered by many of his students.
He would lecture without notes often, sat on the desk, taking us along on a story. One of his lectures was on the idea of the 'Commons' and the changing fortunes of salmon in Canadian rivers.
This Guardian article looks at the decline in migratory fish populations and the impact of human activity.
Another story of collapse - migratory fish populations have crashed by more than 80% since 1970 https://t.co/y3rKQZkrMp
