The wilderness is encroaching over abandoned towns
in the Chernobyl exclusion zone. One of the elderly residents who refused to evacuate the contaminated area says packs of wolves have eaten two of her dogs, and wild boar trample through her cornfield. Scientist are divided as to whether or not the animals are flourishing in the highly radioactive environment: "Robert J. Baker of Texas Tech University says the mice and other rodents he has studied at Chernobyl since the early 1990s have shown remarkable tolerance for elevated radiation levels. But Timothy Mousseau of the University of South Carolina, a biologist who studies barn swallows at Chernobyl, says that while wild animals have settled in the area, they have struggled to build new populations."
