By Josh Cunnings for Enviro News - Well, there you have it. These risks are there and they are all too real. The question is: how many catastrophic nuclear disasters does humanity need to get the point? And how severe do these catastrophes need to be for humans to understand? It’s important to remember that because Mikhail Gorbachev made the incredibly difficult decision to throw about 600,000 men directly at Chernobyl’s ground zero – and due to the incredibly heroic and deadly work performed by those brave young men and soldiers, only about four percent of what could have been released from Chernobyl, was actually released – and even that wreaked untold devastation. How many nuclear disasters must the world undergo, and what must the severity be, in order for humanity to change its ways? Extremely unsafe situations – like reactors downhill from dams, represent only one example of the myriad threats facing nuclear power plants. Nevertheless, old Mark 1s, and many other dangerously located reactors, remain in operation today – despite countless safety concerns. One thing that’s almost certain is if you play with fire long enough you will get burned. Sadly, humans often suffer a form of collective amnesia regarding the severity of these disasters. Hopefully, over time, and with more good reporting and educational programming, that will change.
