Question: Why are Australia, the US, Brazil, Russia and Canada so important in the battle to save our environment? Answer: Because they hold 70 per cent of the world's remaining untouched wilderness areas and urgent international action is needed to protect them.
University of Queensland and Wildlife Conservation Society researchers have produced a global map that sets out which countries are responsible for nature that is devoid of heavy industrial activity. The data exclude untouched wilderness in Antarctica and on the high seas that is not contained within national borders.
In 2016 the team of scientists produced data that charted the planet's remaining terrestrial wilderness and this year it examined which parts of the world's oceans remain free from the damaging impacts of human activity. They found that more than 77 per cent of land — excluding Antarctica — and 87 per cent of oceans have been modified by human intervention.

The researchers say the planet's remaining wilderness can be protected "only if it is recognised within international policy frameworks". They are calling for an international target that protects 100 per cent of all remaining intact ecosystems.
