Sir David Attenborough has been named a Champion of the Earth by the UN’s Environment Programme.
The award recognises the 95-year-old’s commitment to the natural world and climate change.
After accepting the award, Sir David said the world must take action now to protect nature and the planet.
His celebrated documentaries include The Green Planet and A Plastic Ocean.
Sir David said that environmental success stories should give us hope that change is possible.
“We know what the problems are and we know how to solve them. All we lack is unified action.”
UNEP Executive Director Inger Anderson said that the UN chose to recognise Sir David because of his devotion to broadcasting the natural world.
