The United Nations says the protection of tropical rainforests in Papua New Guinea is a global responsibility.
The comment was made by the UN Development Programme's resident representative in PNG during this week's celebration of world environment day.
Roy Trivedy says for people in PNG to prevent deforestation they need financial support from the rest of the world.
He told Ben Robinson Drawbridge about efforts to extend protected areas and threats to conservation in PNG.
