In Wikipedia 86 contestants are listed. But in their official Website there are only 80 photos of delegates minus Denmark, Haiti, Lebanon, Malaysia, Northern Ireland and Papua New Guinea. Miss Earth website needs some updating to include portraits of 4 other delegates who are already in the Philippines--Denmark, Malaysia, Northern Ireland and Papua New Guinea. For Haiti, I think she has not arrived yet as there's no photos of her in their activities except for a short video clip introducing herself; while for Lebanon none at all.
So that makes 84 (or 85 to include Haiti) candidates competing for the title. This solidifies the stature of MISS EARTH as one of the most anticipated, relevant and major international pageants!
