While the world is riveted on Japan’s tragedy, other global menaces are proceeding, barely noticed. One creeping disaster is acidification of the world’s seas, caused by CO2 from burning of fossil fuels.
“The carbon dioxide we pump into the air is seeping into the oceans and slowly acidifying them. One hundred years from now, will oysters, mussels and coral reefs survive?” Elizabeth Kolbert asks that question in “The Acid Sea” in the April National Geographic. She continues:
