Talking common sense, clean-ups and jellyfish with Éanna Ní Lamhna

World Ocean Day is coming up and we can mark it with gorgeous An Post stamps — and by picking up some plastic litter from our beaches and waterways

Nico De Marchis (aged 11) and biologist and environmentalist Éanna Ní Lamhna on Rush Beach, Dublin, as An Post calls on the public to support its Beach and Waterways Clean-Up Day on June 8 and unveils its beautiful new marine life stamps, These marine life stamps are available online at anpost.com/shop or in-store at selected post offices nationwide from Thursday, June 6

"Well, a jellyfish can't make a speech to justify itself to humans so does that mean it shouldn't exist?"

A common reaction to spotting jellyfish on the beaches and in warm water is horror and warnings about stings and dangers. But biologist, environmentalist, author and educator Eanna Ní Lamhna is keen to celebrate all the good things about jellyfish and also pulls no punches in pointing out that we may well be seeing more and more of them through our own actions.
