estuaries feeds back up the river in the end to destroy the source of the river. Showing the interconnectedness of everything on the earth, this was the key element in their task, the purpose of which was showing that the earth itself is a living body in which everything is interconnected, and damage to some of it is damage to all of it."— Alan Ereira. Participation at UN summits The 1990 documentary From the Heart of The World: Elder Brother's Warning was shown at the Earth Summit in Rio de Janeiro in 1992 and was seen to inspire delegates to take action. 'Aluna' was produced in time for another important UN environmental conference, the United Nations Conference on Sustainable Development held at Rio de Janeiro from 20–22 June 2012. Two Kogi Mamos were expected to attend the conference. Production Originally the budget was set at £270,000. Alan Ereira got Bruce Parry interested in the project and Parry met with the Kogi, who agreed to the project. With Parry involved, the BBC offered £180,000 and Indus Films offered a further £20,000. However, when Bruce Parry became 'committed to another project', the offer of funding from the BBC was withdrawn. Therefore, Alan Ereira had to seek alternative funding. Some of this funding came from the British charity The Onaway Trust, which also helped fund Ereira's book on the Kogis, The Heart of the World. The Kogis had their own indigenous film crew, enabling the film to include previously unrecorded holy sites and practices that other film crews had been prohibited from seeing. Throughout the collaboration, the Kogis exercised their autonomy while the film's director, Alan Ereira, looked forward to see what the indigenous crew had recorded. The Mamas took charge of what was going to be filmed and consulted Aluna through divinations. The collaboration between the indigenous crew and the European camera crews enabled Alan Ereira to bring a camera operator and a sound recordist to work with their indigenous counterparts in Colombia. Participation in festivals Aluna was chosen to be shown at the 2012 Sheffield International Documentary Festival where it would have its World premiere.
