The author is Callum Roberts and the subtitle is The Fate of Man and the Sea. It is an excellent look at the environmental problems associated with oceans. Here is one bit:
European seas are far less productive than they once were. The fact that the UK bottom trawl fleet lands only half the fish today that it did when records began in 1889, despite a massive increase in fishing power, says all we need to know about how we have squandered natural capital.
…In 1889, there were ten to fifteen times as many large bottom-living fish like cod, haddock, and halibut in the seas around the UK as there are today.
The book is interesting throughout and very readable, without losing its fundamental seriousness.
