David Attenborough opens nature park on rubbish tip
We're used to seeing wildlife expert David Attenborough doing really exciting things like reporting from the Arctic or the middle of the jungle.
So what if we told you his latest project was a load of old rubbish... literally!
He's helping to transform former rubbish dumps into beautiful nature parks.

The Thurrock Thameside Nature Park
The Thurrock Thameside Nature Park in Essex lies on top of 50 years of waste from six London boroughs, which has been restored to grasslands, woodland, ponds and reedbeds.
It's one of the largest restoration projects ever made by the Essex Wildlife Trust, turning what was a rubbish tip into a haven for bees, birds and reptiles.
Sir David, president emeritus of the Wildlife Trusts, said: "This is the beginning of a new chapter in the history of this part of the Thames Estuary.
"The area has had its ups and downs. This wonderful nature area and the extraordinary new centre stand where there were once 230 Saxon dwellings - but in between times the waste of six London boroughs has been brought here."
