Section 4 of Papua New Guinea’s constitution outlines protective measures for the nation’s natural resources and environment. It reads:
We declare our fourth goal to be for Papua New Guinea's natural resources and environment to be conserved and used for the collective benefit of us all and be replenished for the benefit of future generations.
We accordingly call for:
Wise use to be made of our natural resources and the environment in and on the land or seabed, in the sea, under the land, and in the air, in the interests of our development and in trust for future generations; and
The conservation and replenishment, for the benefit of ourselves and posterity, of the environment and its sacred, scenic, and historical qualities; and
All necessary steps to be taken to give adequate protection to our valued birds, animals, fish, insects, plants and trees.
