According to a new study, only five countries hold 70% of the remaining wilderness in the world.
Researchers from the University of Queensland and Wildlife Preservation The company identified the countries in a study published in the journal Nature.
He said that only 23% of the landmass of the planet can now be considered a "wilderness" – places in which there is no industrial activity. The wilderness areas do not grow back once they are gone.
Here is where the last wilderness of the world is:
Australia: desert
Researchers have identified Australian deserts as one of the last wild areas on the planet.
The Australian deserts are the only home of some animals, but the areas are threatened by climate change, mining and agriculture.
"We have already lost so much, we must seize this opportunity to secure the desert before it disappears forever," the researchers write.

"Wilderness areas face the same extinction crisis as the species. In the same way as the extinction of species, the erosion of wilderness is essentially irreversible, say the researchers.
Most wilderness areas in the United States are in Alaska, which is home to large areas of tundra.
The most serious threat to the tundra of Alaska is climate change, but the construction of oil pipelines and the search for oil and gas, which can kill wildlife, are other threats, according to National Geographic.
Canada: Boreal Forest
The researchers found that Canada's boreal forests were one of the largest remaining virgin wilderness areas in the world.
"TThe boreal forest is the most intact ecosystem on the planet and holds one-third of the world's terrestrial carbon, "according to the study.
However, forests are at increased risk of fire and drought due to climate change, as well as activities such as mining and forestry.

Much of the Brazilian Amazon rainforest has been destroyed by human activities such as logging and rainforest.
But scientists around the world are concerned about the election of Jair Bolsonaro, who said that he wants to travel the largest and most diverse tropical forest in the world.
As president of Brazil, Bolsonaro will control nearly two-thirds of the Amazon, which chills the planet and is home to many indigenous peoples. He argued that too many environmentally protected areas are detrimental to the country's development.

The researchers found that Russia has more wilderness areas than any other country in the world.
They did not include Antartica because activities such as mining were prohibited.
They calculated that 100 years ago, only 15% of the planet's surface was used to grow crops and raise livestock. Today, more than 77% of the land (excluding Antarctica) and 87% of the oceans have been modified by the direct effects of human activity.
