This article ends with a discussion of the impact of the noise of human activity on sea life, and I don't like how it portrays human activity as a negative. "Chronic shipping noise may harm or even break invertebrates’ hair cells, leaving them not only deafened but numb or disoriented." Sounds like they should evolve new, better hair cells soon! Jokes aside, the subtext is "boats are bad". Well, I think global trade is a good thing. How about semantically isolating the noise from the shipping? "The chronic noise from today's shipping may harm ..." Maybe we'll find better propellers.<p>Otherwise great article. First two parts are very interesting. Worth a read. 10/10
