NHS workers going green to offset Covid footprint

Available for over a year

Planet Earth is fast approaching a very dangerous tipping point. In 2021, floods in Germany, Belgium and China have wreaked havoc - killing hundreds. Wildfires continue to devastate parts of North America, Greece, Turkey and Russia. The United Nations says the situation is a code red for humanity. But it says if we act now, a climate catastrophe can be averted. Governments have a huge part to play in tackling climate change - and the hope is they will agree on a plan at the UN’s climate summit in Glasgow in November - COP26. But individuals can play a part too. In the latest episode of our new podcast 5 Minutes On, BBC News Health, Science and Environment correspondent Laura Foster speaks to NHS workers in Cardiff. They've spent the last 18 months trying to protect people from Covid - and are now turning to nature to save the planet.
