WordPress Weekly Photo Challenge: “Dialogue”

It’s your turn now: for this week’s challenge, bring together two of your photos into dialogue. What do they say to each other?

            1. Thanks, Ron. I’m in Gig Harbor visiting my daughter. Good to have sites that relate a bit further north!
              Your suggestions have been added to my RSS feed.
              Disturbing to see the increasing number of challenges faced by the Sound ecosystems.
              Talk about world under stress…

        1. Yes, Ron. Alarming aspect of the Alaska connection is the idea that the syndrome jumped into a different ocean current system. Glad it might be letting up in WA. Scientists who met recently in Newport also noted that more juveniles are being observed. Like you, I hope this all turns around soon…

  1. Good contrast between the photos. First one shows brightly coloured, fully blossoming sea urchins, anemone, and coral (? lower left). A few mussel dishes remain from lunch, while the sea star is reaching for briquettes to start the barbecue. Colourful, vigorous, summer-holiday imagery. The second one is relatively devoid of life forms or gaiety, being mostly limp seaweed and a few urchins gone into hiding. The dead sea star resembles a patient with advanced dementia sitting in a geri-chair, unshaven, unmoving, muscles gone, shoved up against the seaweed so as not to be in anyone’s way. I’d say you’re getting your point across.

    1. Thank you, Dandyknife. I prefer the robust, full-of-life dialogue that you proposed. It was a very startling experience to photograph the sea stars you see in these two photos in the same tidal pool location… only yards apart. The photos were taken at Yaquina Head near Newport. I’m not sure if that was one of the areas you visited on your trip here earlier this year…

    1. Yes, Christina, it will be helpful when the exact causes are determined. The challenges will likely be sizable, though. With solutions that will entail long-term global commitment to changes in the ways humans view our planetary-ecosystems and our use Earth’s resources.
