"The Chernobyl accident revealed the extent to which the Chernobyl nuclear power plant is in operation," he added. It also demonstrated that a possible accident can cross borders and extend the effects to several countries. In particular, the radioactive cloud went through much of Europe, mainly affecting Belarus and Russia, as well as Ukraine. The number of radiation victims, according to the Russian Academy of Sciences, was around 200,000, especially among so-called 'liquidators', Ecologists in Action recalled.

He has also warned that the massacre of this size has a very complex solution: "After the accident the hastily constructed sarcophagus was not as it should be, as in 2014 and 2015 there were decreases in some sections. The reactor core is cast and cannot be demolished, and the French company Areva has installed another colossal sarcophagus."

Closing nuclear power plants is the only way to avoid accidents.

"The only way to prevent accidents such as Chernobyl or Fukushima is to shut down nuclear power stations," the environmental group said. To this end, it has proposed to citizens "unplug" nuclear energy generated in the Biscayan suburban area.

For this purpose, Ekologistak Martxan recommends moving from companies that market nuclear energy to those that only sell renewable energy. And it also produces its own energy. It has also recommended a number of recommendations to reduce electricity consumption "for a day" or "forever": to improve the insulation of homes, to put double crystals in windows, to use natural light wherever possible and to introduce LED light bulbs to illuminate, to install efficient appliances as old appliances are damaged and, finally, to adopt simple consumption habits.
