Great educational series by Seattle Times: SEA CHANGE (about ocean acidification and its effects on sealife) Try to read through this long article to appreciate the problem. There are other articles in the series the URLs to which I will also post. "Acidification wasn’t supposed to start doing its damage until much later this century. Instead, changing sea chemistry already has killed billions of oysters along the Washington coast and at a hatchery that draws water from Hood Canal. It’s helping destroy mussels on some Northwest shores. It is a suspect in the softening of clam shells and in the death of baby scallops. It is dissolving a tiny plankton species eaten by many ocean creatures, from auklets and puffins to fish and whales — and that had not been expected for another 25 years." ----------------- Seattle Times, SEA CHANGE basligiyla etkileyici bir dizi yayinliyor. Konusu okyanuslarin asitlenmesi... Atmosferdeki carbondioksit orani arttikca suda cozunen bu gaz, karbonik aside donusuyor, bu da denizdeki kabuklu canlilarin kabuklarinin erimesine, incelmesine ya da olusmamasina sebep oluyor. Midyesinden planktonuna, yengecinden deniz kestanesine kadar butun kabuklular etkileniyor. Balina gibi canlilarin besin kaynagi olan plankton, beslenme zincirinin bir parcasi. Cok gecmeden butun deniz canlilarini acliga mahkum edecek zincirleme bir etkilesim soz konusu olacak. Bu artan karbondioksidin etkilerinden sadece biri. Makale digerlerine de deginmis. Bu dizideki diger yazilari da paylasacagim.
