The event will be launched by the Conservation and Environment Protection Authority (CEPA).
The highlight of the event will be a solo walk by a climate change advocate, who will walk from the city all the way up to Varirata National Park, which is 48km east outside of Port Moresby.
He will be given an opportunity as a guest speaker at the launch.
The United Nations Global Theme for the 2017 World Environment Day is, “Connecting People to Nature”, which was further translated down to a national theme, which is “Appreciate and Conserve our Land and our Seas”.
