I spent much of Thursday listening to experts from around the world tell the Fair Seas Ireland conference how vital the health of our oceans are in the fight against the climate and biodiversity crises.
From overfishing to masses of plastic and other types of pollution we really could be doing better to protect them and the species that live in them for future generations.
I learned that fish are worth more to us alive as they soak up carbon from the oceans. And that even though so many species are on the brink of extinction, we can turn things around by designating marine protected areas that are properly regulated and policed.
