From the Ted Talk by Triona McGrath: How pollution is changing the ocean's chemistry

Unscramble the Blue Letters

Well today I'm going to tell you about a serious reality that is channgig our oceans called oacen acidification, or the evil twin of climate change. Did you know that the oceans have absorbed 25 percent of all of the carbon dioxide that we have emitted to the atmosphere? Now this is just another great service provided by the oenacs since carbon dioxide is one of the greenhouse gaess that's causing cmtalie cnaghe. But as we keep pumping more and more and more carbon dioxide into the atmosphere more is dissolving into the oceans. And this is what's changing our ocean chemistry. When carbon dioxide dissolves in seawater, it uengreods a number of chemical reactions.
