I dunno Snoking. Seems like a natural balance die off according to which way you "read" the article. A whole lot of maybes, and the gray whale at populations "near record highs" just "may be" the cause of a die off due to lack of food. Yeah, natural selection/balance - N-A-T-U-R-E at work. I really don't see anything of "alert" status with the number of the carcasses being "found" by some select scientific populace than what I myself have observed in various locations around the globe in over 60 years. Sure, there are increases, and there are decreases, and there are terminations of species. It is NATURE, nurturing, feeding, recycling, and that misused word by man - evolving. A plan developed not by man...but is well explained in a particular writing. Maybe you should promote "Carousel" or "Soylent Green"?
If I remember correctly we were supposed to be out of Polar Bears by now. What happened?
