Happy 100th birthday, Sir David Attenborough! And thank you for your lifelong, unwavering commitment to #ClimateAction. “If we take care of nature, nature will take care of us," said the natural historian and broadcaster during the #UnitedNations Climate Conference COP24 in Poland in 2018. "It’s now time for our species to stop simply growing, to establish a life on our planet in balance with nature, to start to thrive." You too can #ActNow and join him in protecting our planet. Small everyday actions — like recycling, driving less and reducing food waste — can make a big difference. 📸: UN Social Media / Esra Sergi
