Biodiversity
Many species of insects, bacteria, and fauna have thrived amid the emission of 4,000 times the radiation that was released in the nuclear bombing of Hiroshima. Cameras set up by the TREE project (TRansfer-Exposure-Effects), led by the Centre for Ecology and Hydrology in the UK, have shown abundant amounts of fauna, including in areas with the heaviest radiation, in the exclusion zone. Studies indicate that insects that have been exposed to the worst of the radiation effects of Chernobyl appear to have a shorter life span.
Radiation Remains A Problem
Although it can be tempting to look at the bright side of the equation for wildlife species, it is important to note that in a disastrous situation, the animals survive in most situations and not because of it. Part of the explanation that many species could sustain their size or even expand is speculated to be because the catastrophe wiped out many of their natural predators and rivals.
