Five countries hold 70% of world's last wildernesses, map reveals

First map of Earth's intact ecosystems shows just five nations are responsible for most of them - but it will require global action to protect them

Just five countries hold 70% of the world's remaining untouched wilderness areas and urgent international action is needed to protect them, according to new research.

Researchers from the University of Queensland (UQ) and the Wildlife Conservation Society (WCS) have for the first time produced a global map that sets out which countries are responsible for nature that is devoid of heavy industrial activity.
