One-third less hungry

It never ceases to amaze me that some pieces of research are necessary. In the latest report from the Annals of Unsurprising Research, comes a study that shows that preventing humans from fishing is good for the other fish-eating animals. A study published in Proceedings of the Royal Society says that breeding African penguins spent one-third less time looking for food within three months of closing a 20-km zone to purse-seine fisheries around a major colony, while birds in a comparable colony 50km away increased their foraging effort.

Quantifying this sort of thing is probably helpful, but is it really that surprising?
