A camera crew filming an Our Planet documentary on the flora and fauna within the Chernobyl Exclusion Zone has managed to capture footage of wild animals roaming freely in the deserted area. The cameramen even managed to film rare Przewalski's horses pacing slowly along the abandoned streets. But the surprises didn't end there; a pack of wolves was also spotted roaming in the forest. Their return, the documentary states, could be attributed to the forest teaming with life. According to the programme, the prevalence of wolves within the zone is seven times that of the surrounding region due to the near-complete absence of their principal rival apex predators: human beings.
