Sardine population plummets along U.S. West Coast — AP: Collapse of species feared

18. What I find intriguing.....

...is the species-specificness of these mass die-offs. Unlike clearly man-made kills from pollution where we kill everything in sight, these die-offs are most often explained as ''normal'' environmental impacts, due to salinity, temperature, etc. And yet no one can say why when this occurs other species often go unaffected. Species that eat the same or similar foods, inhabit the same areas and interact with the other flora and fauna of their environments similarly, and yet the die-offs will many times only happen to specific species as in this case. Just sardines. Just starfish. Just baby sea lions. Just grunts. Just orange-tipped black birds.

- Over and over again, it's the same phenomenon.....
