As we get closer and closer to the end of 2020, we’ve been asking Newstalk listeners what the 20 most influential moments of the last 20 years are… We had the first Black President of the United States, the Queen in Croke Park, a new currency, Brexit, a pandemic… Over the next few weeks, we’re focusing on one of the Top 20 each day – and today we focused on Climate Change. Shane Coleman asks environmentalist Cara Augustenborg if it's too late to save the planet while Kieran Cuddihy finds out whether it's really possible to live sustainably. Sean Moncrieff talks to Ocean Rebellion activists Sophie Miller and Rob Higgs. Pat Kenny asks whether youth climate change activists are making any real difference and Andrea Gilligan talks to Flossie Donnelly, dubbed 'the Irish Greta Thunberg!'   Check out newstalk.com/20moments for more   Listen and subscribe to 'The 20 most influential moments of the last 20 years' on Apple Podcasts and Spotify.    Download, listen and subscribe on the Newstalk App.    You can also listen to Newstalk live on newstalk.com or on Alexa, by adding the Newstalk skill and asking: 'Alexa, play Newstalk'.
