How many pristine places are left undisturbed by oil, gas and mining activities, as well as land development? What is the extent of this damage to habitats? According to a study published in the journal ‘Frontiers in Forests and Global Change’, nearly 3 % of the world’s land remains ecologically intact. These areas include Canada’s boreal forests, Greenland’s tundra, Amazon and Congo tropical forests, and the Sahara Desert. Only 11 % of the areas identified by the international research team are under protection.
