UK's Prince William and naturalist Sir David Attenborough have launched a global environmental prize.
It is hoped that the 'Earthshot Prize will motivate climate enthusiasts to come up with 50 solutions to the gravest environment problems by 2030.
Five, one million-pound prizes will be awarded each year for the next ten years.
In a statement, Prince William said: 'the next ten years present us with one of our greatest tests – a decade of action to repair the Earth.'
