In a polluted area, extremely dangerous to human life, the wildest horses in the world gallop freely.
Throughout the Chernobyl exclusion zone, Przewalski's horses – originally from Mongolia, sandy-colored and once on the verge of extinction – were brought in in 1998 as part of an experiment and have been grazing freely in a radioactive landscape larger than Luxembourg ever since.

On April 26, 1986, an explosion at a nuclear power plant released radiation across Europe and forced the evacuation of entire cities, displacing tens of thousands of people. It was the worst nuclear disaster in history, leaving a vast area of ??the Old Continent empty but not dead.
Four decades later, Chernobyl remains very dangerous to human life. But in the absence of humans, wildlife has taken over.

With the disappearance of human pressure, the landscape in the large blocked area has returned to that of centuries ago.
The transformation of the landscape is visible everywhere. Trees sprout from abandoned buildings; clumps of young trees “swallow” the streets; faded Soviet-era signs stand half-hidden in lush vegetation.

Wolves now roam the vast buffer zone between Ukraine and Belarus, while brown bears have returned after more than a century. Packs of lynx, red deer, roe deer, wild cats and even wild dogs have made an impressive recovery.

"The fact that Ukraine now has a free-ranging population of 'taki' (as these unique Mongolian horses are called, which differ from domestic breeds in that they have 33 pairs of chromosomes, compared to 32 for domestic horses) is a small miracle," says Denis Vishnevsky, the area's chief environmentalist.

Hidden cameras have caught horses adapting in unexpected ways. They seek shelter in dilapidated barns and abandoned houses, using them to escape harsh weather and insects – and even to lie down inside.

Despite the radioactivity present, scientists have not recorded any mass deaths, although the effects are evident. Some frogs have developed darker skin, while birds in areas with higher radiation levels are more likely to develop cataracts.
Nature has also adapted to the radioactive reality, although new threats have now emerged.

The Russian invasion of Ukraine in February 2022 was followed by fighting in the isolated area, as troops advanced towards Kiev, digging fortifications in the contaminated soil.

Fires caused by military activity have scorched forests. Scientists report an increase in the number of fallen trees and dead animals – victims of both the extreme winters and the makeshift trenches.

“Most forest fires are caused by drones that crash,” explains Oleksandr Polisuk, head of a local fire department. “Sometimes we have to travel tens of kilometers to reach them.” The fires can release radioactive particles into the atmosphere.

"For those of us who are concerned with environmental protection and ecology, it's something wonderful," says Wisniewski. "This area was once heavily exploited for agriculture, cities, infrastructure. But nature has managed to restore it to its original state." / Associated Press.
