The International Day of the World's Indigenous People is observed on 9 August every year, to highlight and address the problems faced by indigenous peoples regarding human rights, environment, education and health.
The theme for 2015 focuses on access to healthcare, which remains a major challenge. "On this International Day of the World's Indigenous Peoples, I call on the international community to ensure that they are not left behind. To create a better, more equitable future, let us commit to do more to improve the health and well-being of indigenous peoples," UN Secretary-General Ban Ki-moon said in a statement.
To celebrate the day, here are ten interesting facts about indigenous peoples:
