Nature can survive radiation but can she survive us?

Four years after a tsunami destroyed the nuclear power plant and 160,000 people were evacuated from their homes in Fukushima nature has reclaimed the land. Although 120,000 have still not been allowed back home trees and plants are growing exuberantly. This is even more evident at Chernobyl where the nuclear accident occurred 30 years ago. Here no human being has returned but the place is teeming with wildlife. Wolves are 7 times the number compared to surrounding nature reserves. It indicates 2 things - 1. If predators are so abundant it means that the prey are also healthy and multiplying and 2. Humans are a greater threat to animals than deadly radiation. Nature quickly reclaims any place that is deserted by humans, often with surprising results. Higher rates of thyroid cancer have been discovered in children who were near Fukushima at the time of the accident. Thyroid concentrates iodine so the power plant must have released a large dose of radioactive iodine at the time of the accident. The 2 bombs at Hiroshima and Nagasaki and the many accidents at nuclear power plants means that effects of radiation on humans have been studied extensively. People worry about the harmful effects of X Rays, used extensively by doctors to diagnose everything from pneumonia to broken bones, although the radiation from diagnostic tests is minuscule compared to that from a nuclear accident. We know that radiation can damage DNA, which constitutes our genes, and can cause anything from birth defects to cancer. Skin cancer is much commoner in white skin people who try to get a tan by exposure to the sun or even a sunbed. How then are plants growing where human beings are forbidden to go? And if plants are relatively resistant to radiation what about mammals, such as wolves? Germ cells, such as ova and sperms, and unborn fetuses are exquisitely sensitive to radiation so it is fantastic that so many species of mammals are breeding and look so healthy. There maybe 2 explanations for normal looking animals. First, deformed babies born to animals will not survive, so nature is selecting only the normal ones to become adults. Second, animals within the radioactive zone are sterile but the safety of the zone, because of the absence of human beings, with abundant food supply is attracting animals from surrounding areas. This is proof, if any proof is required, that we humans are super predators. We not only kill for food but for fun as well. What fun did this dentist get from killing Cecil the lion? How perverse! Our cruelty is easy and without any remorse. Sharks have their fins cut off and are then thrown back into the sea to drown. Legs are chopped off from living frogs because they are considered a delicacy in some parts of the world. But the biggest enemy of wildlife is agriculture, in which forests are cut down, reducing habitat, pesticides poison animals and increased CO2 is heating the oceans, bleaching corals. We should be proud. We are more dangerous than nuclear radiation.
