Untouched nature is a beautiful pair of words for which there will soon be no equivalent in real life. Scientific journal Naturessa according to a published study, man has destroyed about 1.9 million square kilometers of nature in 13 years.

The researchers used satellite imagery to compare the change between 2000 and 2013. They found that, in effect, an area the size of Mexico, rich in biodiversity, has disappeared somewhere under highways, industrial sites and housing.

– We knew how to expect a significant part of untouched nature to be destroyed, but still the results were a shock, the head of the research group Brooke Williams said The Guardianille.

Russia, Canada, Brazil and Australia are the largest countries that still have untouched nature. They account for about 60 percent of the world’s regions.

– We learned that significant parts of the ecosystem had disappeared in just 13 years. It’s awful to think about it. According to our research, human impact extends deeper and deeper into nature, Williams continued.

Tropical grasslands had suffered the most. But even at colder latitudes, the human footprint was clearly visible. One of the saddest examples is, of course, the cutting of jungles into farmland.

In Sumatra, for example, the rainforests kept at home by oranges, tigers, elephants and rhinos have practically already been cleared to the ground.

– The investigation is not lying. Man shrinks nature so that there is no more living space for other species, the scientist James Watson continued.

Of the 221 countries in the world, only 26 had at least half of the land in its natural state.

– Protecting the Earth’s ecosystems from humans would also be the best way to combat climate change. But we won’t succeed without addressing population growth and consumption issues at the same time, Williams concluded.
