Why read this: This article gives B2 readers a clear example of how a long-form science feature handles a question without a tidy answer. Most students already know Chernobyl as a disaster story, so the text builds on that schema and pushes them past the simple narrative. They see three named scientists with overlapping but different positions, plus a large counter-explanation (humans left, so animals returned). It is a useful chance to read journalism that argues a careful, hedged point, while the vocabulary and sentence structures stay within reach for upper-intermediate learners.
What to notice: Notice how the article keeps shifting between two competing readings: radiation has changed Chernobyl's wildlife in striking ways, and the picture is more complicated than that. Watch for hedging language such as 'may', 'might', 'suggestive rather than conclusive' and 'no hard proof'. These signals tell readers that scientists are still uncertain. Also notice how each new piece of evidence (darker frogs, bank voles, dark fungi) is followed by a sentence that complicates it, usually through the voice of a critical or cautious expert.
Skills practised: Readers practise tracking a debate across paragraphs and weighing competing claims rather than collecting facts. They work on inferring the writer's overall stance from word choice and structure, even though that stance is never stated directly. Multi-word phrases such as 'exclusion zone', 'hard proof', 'pushes back against', 'transgenerational mutations' and 'withdrawal of humans' are glossed in the margin so students can build domain vocabulary while reading. The MCQs target literal recall, inference about cause, and main-idea comprehension, and the open questions ask students to evaluate the evidence and explain how the article uses expert disagreement to show that the science is unfinished.
Chernobyl at 40: how its wildlife has really changed
Forty years after the explosion, scientists agree the exclusion zone is full of life. They still disagree about what radiation has actually done to it.

Late one night in 2016, scientist Pablo Burraco walked through dark woods near the ruins of the Chernobyl , the site of the world's worst . After the in 1986, the area was emptied of people for many miles, leaving the forest unusually quiet. Following the call of a small male , he moved closer and gently lifted the 5cm amphibian from its branch. Burraco, an at Donana Biological Station in Spain, was on his first to the zone.
In his hand, the frog looked slightly darker than the same species living further away. The difference raised a question scientists have asked for forty years: had radiation from the damaged plant changed the animals living near it? Reactor number four exploded on 26 April 1986, and winds carried as far as the UK, Norway and parts of North Africa. The land closest to the plant in northern Ukraine received the heaviest dose, and intense hotspots still remain.
Many people feared that would destroy nearby plants and animals, but while humans left, the wildlife could not. Forty years later, it is clear that many species are living quite well inside the 37-mile-wide . That does not mean nothing has changed: researchers have recorded twisted trees, swallows with tumours, and a strange black fungus inside the radioactive ruins of the reactor. Whether some creatures have actually adapted to cope with contamination is .
Burraco and his colleagues have sampled more than 250 tree frogs over the years. In 2022, they reported that frogs inside the exclusion zone were, on average, darker than those outside. Their hypothesis is that higher melanin levels, the pigment behind the dark colour, may act as a partial shield against radiation, although there is no . Timothy Mousseau, a biologist at the University of South Carolina, argues that the sample was too small and that today's radiation levels do not match the colouring. Burraco this, noting that radiation has fallen sharply since 1986.
Carmel Mothersill, a radiobiologist at McMaster University, says the 2022 study is methodologically sound, but she also raises a wider question. How can anyone be sure an unusual feature was caused by radiation rather than other pollutants such as ? Similar uncertainty surrounds genetic patterns in and the unusual diversity found in the cells of . Many pine trees, especially sensitive to radiation, died after exposure, and birch trees later , producing a very different forest. Animals respond to that new environment, which may itself explain some differences rather than radiation alone.
One change is rarely disputed: the sudden . Where people once farmed and lived, wolves, bears, deer, and elk now move freely. The number of wolves in the zone may be seven times higher than in nearby , probably because prey is plentiful. The Eurasian lynx has returned, and a photographed a brown bear in 2014, the first sighting in more than a century. Dogs descended from pets abandoned in 1986 still live in the area, often cared for by the guards.
Could plants and animals near Chernobyl have truly evolved to cope with radiation? This is the most controversial claim of all. A 2012 study suggested local soybeans had adapted, and bank voles in the zone show greater resistance to . Some fungi clearly turn darker under radiation, which Mousseau says is positive evidence that melanin offers protection from . Mothersill is more interested in , the idea that genetic changes from 1986 have been to later generations. Recent work warns that radiation combined with is straining Chernobyl's barn swallows. Forty years on, the picture is neither tragedy nor triumph. It remains complicated and unfinished.
