Our Planet Reviewed - Expedition Papua New-guinea

la planète revisitée

 

Naturalists and systematic biologists have travelled the world for more than 250 years now in order to discover its flora and fauna. Thanks to the patient efforts of generations of scientists, about 1.8 million species are today known and can be described. However, the scope of the tasks still to be accomplished remains enormous: according to estimations, there are still between 8 and 30 million unknown species on our planet. But time is of the essence since the sixth big extinction has already begun. A large number of these organisms are already seriously threatened and many will have already disappeared before they have even been discovered.

Context

The first naturalist expeditions with the aim of scientifically describing the living world date back to the middle of the 18th century. Two hundred and fifty years later, biologists thought that they had identified half of the inventory of animal and vegetal species populating the planet.

Objectives

The results obtained within the frame of the expeditions “Our Planet Reviewed” will allow for the completion of knowledge about marine as well as terrestrial biodiversity. They will also serve to create the tools which are required for the establishment of politics of conservation adapted to the respective regions by the NGO and the governments of the host countries.

Destinations

At the end of the 1980ies, a revolution took place in the area of the biology of conservation. Its beginning was the question of a researcher, Norman Myers: “In which area of the world does a dollar spent have the biggest effect on slowing down current extinction?”

Methods

The initiative “La Planète revisitée” does not result from a spontaneous generation. As heir of the great naturalist expeditions of the past, it is based on proven know-how, the quintessence of which is expressed in the expedition “Santo 2006”.

Eductional component

Journeys to our planet reviewed feature more often than not an educational component which allow teachers to develop a class projet, should they wish to do do. This educational project is open to all teachers, from primary school and secondary school.
