(Newser) – A group of whales in Canada is being stressed out by noise emanating from ship traffic, a new study suggests, and the stress may be harming the whales' immune system and making it harder for them to reproduce. Scientists measured the stress hormones in the poop of right whales in the Bay of Fundy and discovered that whales are less stressed when fewer ships sail the area, reports LiveScience.

"What this study has shown is that they are having a measurable physiological stress response to the noise in their environment," says one researcher. The whales in question communicate across long distances using low-frequency sounds, similar in frequency to the tones produced by nearby ships.

The study "suggests"? It must be a very preliminary study, if it can only suggest. I can suggest that high gas prices cause stress in humans and may make it harder for them to reproduce. The problem is I can't prove it and this study can't yet prove anything either.

I don't know about this study but after yesterday's burritos I had a whale of a poop and released plenty of greenhouse gases....
