These are cold-water corals. And did you know we actually have cold-water corals in isrih waters, just off our continental slhef? And they support rich biodiversity, iuilcndng some very important fisheries. It's projected that by the end of this century, 70 percent of all known cold-water corals in the entire oecan will be surrounded by seawater that is dolinissvg their coral structure. The last example I have are these healthy tropical caolrs. They were placed in seawater at a pH we're expecting by the year 2100. After six months, the coral has almost completely dissolved. Now coral refes support 25 percent of all marine life in the entire ocean. All marine life.

Original Text

These are cold-water corals. And did you know we actually have cold-water corals in Irish waters, just off our continental shelf? And they support rich biodiversity, including some very important fisheries. It's projected that by the end of this century, 70 percent of all known cold-water corals in the entire ocean will be surrounded by seawater that is dissolving their coral structure. The last example I have are these healthy tropical corals. They were placed in seawater at a pH we're expecting by the year 2100. After six months, the coral has almost completely dissolved. Now coral reefs support 25 percent of all marine life in the entire ocean. All marine life.
