Noise from ships stresses whales nearby, researchers have shown.

Ships' propellers emit sound in the same frequency range that some whales use for communicating, and previous studies have shown the whales change their calling patterns in noisy places.

Now, researchers have measured stress hormones in whale faeces, and found they rose with the density of shipping.

What would you have us do? Dump a bunch of Zoloft in the ocean?
