I don't know which endangered species to write about today

Some days, there are too many endangered species in the news for me to write about just one of them.

Today, I could easily write about the Feds cutting the protected habitat for yet another species, this time the peninsular bighorn sheep, which is about to lose nearly half its habitat in the name of economics.

Or maybe I could write about Montana taking the right step and cutting the number of wolverine trappings allowed during its upcoming hunting season. (Who the heck would want to trap a wolverine, anyway?)

The possible expansion of protections for endangered Atlantic salmon also warrants discussion, as does an agreement to protect the largest freshwater fish in North America, the endangered Kootenai River white sturgeon.

How could I not write about Russia's Vladimir Putin helping to tranquilize a rare Amur tiger and fit it with a radio-tracking collar? You don't get stories like that every day.

And there's so much going on in Australia, where 23 kangaroo and wallaby risk extinction. Meanwhile, efforts are underway to track and better understand the last 140 western ground parrots before they disappear forever. Saturday is Australia's National Threatened Species Day, an important date for a country where 20% of its unique species face extinction.

Then there's the really horrible news, the evidence that bottlenose dolphins are killing other dolphins and porpoises as they compete for food around the British isles. I've written about overfishing many times before; is this the next sign that the oceans are being depleted by the voracious appetites of overpopulated humans?

Finally, on a broader scale, new research to be published this week in the Proceedings of the National Academy of Science suggests that we are in the middle of the greatest extinction event ever, with species disappearing at 1,000 times the rate normally found in nature. Not good. Not good at all.

Oh well. Today, I'll just have to settle for an overview of what's going on with all of these different species. Maybe there won't be quite so much news tomorrow... But somehow, I doubt it.
