The mayor of the Amazonian province of Orellana in Ecuador, Anita Rivas, is coming to London today to deliver a heartfelt appeal to the UK government: "Save the Yasuní National Park by helping keep its oil underground".
The Yasuní is one of the most biodiverse places on the planet and is home to some of the world's last indigenous groups living in voluntary isolation from the outside world.
But it is under threat from oil companies desperate to start drilling up the half a billion barrels of oil underneath it. Exploiting Yasuní's oil would destroy this UNESCO reserve and will result in significant loss of life for its inhabitants. All this for a mere five days' oil for the rest of the world.
