Environmental security

Do humans cause more environmental damage than a nuclear disaster?

At a temple in Fukushima thousands of sunflowers have been planted to help fight the radiation. "It is as if an invisible snow had fallen on Fukushima and continued to fall, covering the area," said Koyu Abe, chief monk at the Buddhist Joenji temple. Sunflowers were used near Chernobyl after the 1986 nuclear accident to extract radioactive caesium from contaminated ponds nearby. Japanese scientists are carrying out tests to prove their usefulness in fighting radiation. Picture taken August 6, 2011.

Recently, together with other scientists, I studied the animals in the human exclusion zone around the plant.
The results were shocking: whatever the impact of radiation on animals may be, the effects of human habitation seem to have been a lot worse. The site offers a stark reminder that humans’ simple, physical presence in a habitat is more damaging than one of the twentieth century’s worst environmental catastrophes.
