Ukraine will introduce European bisonto the Chernobyl area affected by a nuclear power disaster to establish a nature reserve, the country`s Emergency Situations Minister Volodymyr Shandra announced Friday, according to Xinhua.

    "I think we will bring up to ten bison to the zone to raise the biological diversity of the territory," Shandra said at a press conference.

    He also urged that tourists be encouraged to visit the Chernobyl area so that people can observe the "price of human error."

    On April 26, 1986, the world`s worst nuclear accident occurred at the Chernobyl nuclear power plant in Ukraine, causing widespread environmental pollution.

    In recent years, the Chernobyl exclusion zone has become a haven for wildlife with lynx, eagles, and even bears that had disappeared from the area, reappearing. In addition populations of badgers, deer, elk, otters, wolves, beavers and boars have thrived without human interference.
