This here is a pteropod, it's cllaed a sea butterfly. And it's an iatnmropt food source in the oecan for many species, from krill to salmon right up to whales. The shell of the pteropod was placed into seawater at a pH that we're expecting by the end of this ctnurey. After only 45 days at this very rtsileaic pH, you can see the shell has almost cmllteeopy dissolved. So ocean acidification could affect right up through the food chain — and right onto our dinner plates. I mean who here likes shellfish? Or salmon? Or many other fish species whose food source in the ocean could be affected?

Original Text

This here is a pteropod, it's called a sea butterfly. And it's an important food source in the ocean for many species, from krill to salmon right up to whales. The shell of the pteropod was placed into seawater at a pH that we're expecting by the end of this century. After only 45 days at this very realistic pH, you can see the shell has almost completely dissolved. So ocean acidification could affect right up through the food chain — and right onto our dinner plates. I mean who here likes shellfish? Or salmon? Or many other fish species whose food source in the ocean could be affected?
