  •  Dying frogs are an early warning that our precious (29+ / 0-)

    ecosystems are collapsing.

    We should heed this warning, but probably will not. Perhaps one day earth will evolve an intelligent species able to live in sustainable harmony with our environmental systems.

    •  Frogs are having other problems, too (6+ / 0-)

      I would imagine endocrine disruption could also interrupt reproduction, and reduce populations.  I've been following this for a couple of years:

      Sex Reversal In Frogs An Effect Of Drugs In The Environment

      “This is the first clear evidence that estrogen in nature really can have a detrimental effect on frogs. Previous studies have used considerably higher concentrations than are normally found in nature,” says Cecilia Berg.

      New study points to agriculture in frog sexual abnormalities


      The Frog of War - Atrazene
      When biologist Tyrone Hayes discovered that a top-selling herbicide messes with sex hormones, its manufacturer went into battle mode.

      About a third of the exposed males had malformed reproductive organs. Many were hermaphrodites, with both ovaries and testes. Some had more than two of each organ—and some of the testes produced eggs instead of sperm.
      Today, atrazine is used in more than 60 countries around the world -
      in Africa, North and South America, Asia and the Middle East. No country has ever discontinued the use of atrazine based on health effects.

      It's difficult to be happy knowing so many suffer. We must unite.

        super pesticides mimic estrogen. Is the adjective they used estrogenic?

        When I was a young student of computer simulation modeling decades ago at MIT I adapted and build some illustrations of how the long-half lives of one of the three classes of pesticide, such as DDT meant they could persist in ecosystems and continue to increase their concentration in estuaries even 10 years after they were banned in the US after nearly driving eagles and other birds extinct. (The original models had been developed by the Meadows.)

        While DDT, and some of the other most pernicious pesticide in this major problematic third class of more complicated estrogenic class of chemicals were banned in the US, but chemical manufacturers ended up just moving them offshore to developing countries where they devastate fragile ecosystems.

        We need to demand that chemical companies become more responsible corporate citizens and do more to hold themselves accountable, as they have money, the PhD talent, motivation, and internal coordination networks so superior to citizen volunteers we are vastly outgunned in terms of lobbying politicians and even public opinion.

        Its so bad that I fear when many people hear speeches promoting "greener" approaches to the environment they go out and buy gallons of self spray lawn chemicals to do their part. And, not bother to even wonder if the woman two houses downwind on application day, might be pregnant with the window open.

        Awareness of the potential of mishandling of chemicals ought to be a major champaign sponsored by "wiser" chemical companies that wanted to exercise real leadership in a more modern conception a responsible members of our communities.    

        Instead I heard on NPR that chemical companies have hired lobbyists and "trackers" for every single employee of the EPA to monitor every publication, letter to the editor and any other activity that might lead to greater regulation.

        We both would probably have files opened up on us just for this comment exchange, WOR, if it weren't for the fact we no doubt are already in several databases on account of prior work and public interest activism.
