    This is a view inside the mouth of a leatherback sea turtle. Those pointy things aren’t teeth but fleshy papillae used to help it capture and swallow jelly fish.

    …and…of course…they are endangered for all the usual reasons. Including Plastic.

    They survived the extinction of the dinosaurs. They’re descendants of one of the oldest family trees in history, spanning 100 million years. But today leatherback turtles, the most widely distributed reptiles on Earth, are threatened with extinction themselves, in large part due to the carelessness of humans…

    …Since leatherbacks prefer eating jellyfish, it’s widely believed they mistake bags or other plastics for their meals. Since jellyfish and marine debris concentrate where ocean water masses meet, leatherbacks feeding in these areas are vulnerable to ingesting plastic.

    Once leatherbacks ingest plastic, thousands of spines lining the throat and esophagus make it nearly impossible to regurgitate. The plastic can lead to partial or even complete obstruction of the gastrointestinal tract, resulting in decreased digestive efficiency, energetic and reproductive costs and, for some, starvation.

    “Plastics ingestion doesn’t always cause death, but there are clearly health risks to the turtles,” says Dr.James.

    ….Leatherback turtles are classified as critically endangered world-wide. The true population size is not precisely known, as only adult females come ashore for nesting in remote tropical locations. During the summer and fall, Canadian waters support the highest density of foraging leatherbacks in the North Atlantic.

    Yes, our destruction of the biosphere continues unabated.

    Everyone should really enjoy awesome creatures like the leatherback sea turtle while they can because we will likely be the last generation to see them.

    Yeah, the great diversity is awe-inspiring but what I like is that I share ancestry with all the myriad creatures that comprise that great diversity. It’s the interrelatedness of it all that gets me. I share ancestry with the tapir, giant squid and the redwood tree. I share ancestry with millions of species living and extinct. That includes every species that is living or has ever lived. They are all relatives.

    On the other hand, that makes sending Xmas cards a chore…

    Yes extinctions happen, but extinctions on a mass scale like we are seeing today only occur due to some great natural catastrophe…meteors, widespread volcanism, the advent of O2, etc. The earth is in the midst of it’s sixth mass extinction. 50% of the world’s wildlife has been lost in the last 40 years. And unlike the mass extinctions of the past this one is completely preventable because it’s not being caused by a meteor impact but by human activity.

    Well, goody for YOU, Mr. Nittany.

    I am not related to those critters.

    For a Coming Extinction Related Poem Content Details

    BY W. S. MERWIN

    Gray whale
    Now that we are sending you to The End
    That great god
    Tell him
    That we who follow you invented forgiveness
    And forgive nothing

    I write as though you could understand
    And I could say it
    One must always pretend something
    Among the dying
    When you have left the seas nodding on their stalks
    Empty of you
    Tell him that we were made
    On another day

    The bewilderment will diminish like an echo
    Winding along your inner mountains
    Unheard by us
    And find its way out
    Leaving behind it the future
    Dead
    And ours

    When you will not see again
    The whale calves trying the light
    Consider what you will find in the black garden
    And its court
    The sea cows the Great Auks the gorillas
    The irreplaceable hosts ranged countless
    And fore-ordaining as stars
    Our sacrifices

    Join your word to theirs
    Tell him
    That it is we who are important

    You’re equating wildlife loss with extinction. The two are not the same. FYI more than 99% of all species that ever lived on earth are extinct.

    Yes, I’m aware that 99% of all species that ever existed are extinct and I’m also aware I wasn’t specifically talking about extinctions when I quoted the loss of wildlife. It was just to illustrate how extreme our impact is on other life forms. Normal ‘background’ extinction rates are about 1 to 5 species per year. They estimate the current extinction rate is somewhere between 1000 and 10,000 times that rate.

    Your post did not make such a distinction since it was bracketed before and after with discussion of mass extinctions. To the casual reader it would be very misleading and that is the modus operandi of fear mongering this subject. Also the current extinction rate you quote is further fear mongering and utter BS.

    Guys

    Do me a favor.

    Trim the quoted material in your posts before posting. It’s easy. I have been doing it for you. But you can do it yourselves. Just blue out then delete the excess.

    A lot of the time, the reason posts look readable and orderly is because a mod edited it. (Though more mods should be doing that as a matter of course, at least with their own posts.)

    So it’s very simple and easy to cut down on the number of quotations included per post. I would appreciate help with that because sometimes I, too, just want to read things and think about them without constantly playing janitor.

    There is some difficulty estimating extinction rates. A lot of it is done with computer modeling because physically inventoring species is problematic. Therefore you will see disparity between one researcher’s estimate and another. However, both the research and computer models agree that extinction is happening at a much greater rate than what can be attributed to background extinctions.

    Here is one paper on extinction rates from “Science”. I couldn’t find a free copy online so I posted it from my researchgate account. Hopefully it is viewable.

    EDIT INTERVENTION, ZN: the link is problematical for a lot of reasons so I have a “paint” version:

    I really like that sentence. For some strange reason, it makes me think of Gerald Manley Hopkins:

    The Windhover

    By Gerard Manley Hopkins
    The Poetry Foundation: The Windhover

    To Christ our LordTo Christ our Lord This epigraph dedicated the poem to Jesus while echoing the Latin phrase, Ad Majorem Dei Gloriam, the Jesuit motto meaning “To the Greater Glory of God.”

    I caught this morning morning’s minion, king-
    dom of daylight’s dauphin, dapple-dawn-drawn Falcon, in his riding
    Of the rolling level underneath him steady air, and striding
    High there, how he rung upon the rein of a wimpling wing
    In his ecstasy! then off, off forth on swing,
    As a skate’s heel sweeps smooth on a bow-bend: the hurl and gliding
    Rebuffed the big wind. My heart in hiding
    Stirred for a bird, – the achieve of, the mastery of the thing!

    Brute beauty and valour and act, oh, air, pride, plume, here
    Buckle! AND the fire that breaks from thee then, a billion
    Times told lovelier, more dangerous, O my chevalier!

    No wonder of it: shéer plód makes plough down sillion
    Shine, and blue-bleak embers, ah my dear,
    Fall, gall themselves, and gash gold-vermilion.

    Nittany,

    No, the caption was attached to the photo. I didn’t care for it myself because the “when young” part is redundant since the caption already mentioned it’s a chick. I do like the poem though.

    I also like the name of the bird. Ceroneous mourner. I like melodic names. My all-time favorite is Serratia marcesens.

    Lovely, right?

    It’s a bacterium found in your GI tract that we’ll sometimes isolate from urine specimens when the patient has a UTI. 😉

    A great deal of the best English-language poetry from the 17th through the 19th century was filled with apparent knowledge of birds, botany and biology. And alliteration, too.

    Not sure how much came from the GI tract, though. James Joyce in the 20th century, however, utilized GI in his great novel, Ulysses. He had a lot of guts.
