The Prince of Wales has described those in the running for his environmental Earthshot prize as "heroes of our time".
Prince William will travel to Rio de Janeiro next month for the ceremony - the first time the awards have been hosted in Latin America. The prize, created by the prince five years ago, awards £1m every year to five projects for their environmental innovations.
There have been almost 2,500 nominees this year from 72 countries - this year's winners will be chosen by Prince William and his Earthshot Prize Council which includes the actor, Cate Blanchett and Jordan's Queen Rania.
This year's list of finalists range from a Caribbean country to small start-up businesses.
