The surface layers of the oceans are currently believed to be the world's largest carbon sink, absorbing about 2 billion tons of carbon a year, the equivalent to perhaps a third of human carbon emissions, thus reducing their impact. is not lethal, but has negative impacts on copepod physiology, which in turn may alter marine biogeochemical cycles. i have no copepods in my tank.
