       And, finally, there is the possibility of just burying the waste deep enough that future generations would not even be aware of it and would not be threatened. The Posiva project in Finland calls for a repository that is sixteen hundred feet underground. After the repository chambers are filled, the access shafts would be filled with rocks and concrete. The landscape over the repository would be landscaped and the repository could be safely forgotten.
      In response to the critics of their plan, Posiva says, “It would take years to dig with a material that probably doesn’t actually exist. And the site is not interesting in terms of mining resources. Also, you should note that after the next ice age, there will no longer be any city or building in Europe anyway. Everything will have disappeared under a mile of ice. So, any question (on the necessity to communicate its presence for thousands of years) is completely hypothetical.”
       On the other hand, a future civilization might have some use for nuclear waste. If they have the technology to dig sixteen hundred feet for an unmarked geological repository, they will likely have the understanding and technology necessary to safely handle nuclear waste.
       There was a conference in France on this same subject in 2014. A report that preceded the conference said that “the approach of trading the topic of radioactive waste through mystical tales could be interesting, as the core of the message can be packaged in stories that deal more with fundamental existential themes (creation, death, size, freedom, etc.) and less with daily political or ideological topics.”  
      My fear is that none of these things will be done. If we are facing the decline of our civilization as has been claimed by many scientists, there will also be a decline in funding for these kinds of projects and a decline in political will to carry them out. There are many places around the world where nuclear waste is being stored. There are many places where the development of nuclear reactors and nuclear weapons have left areas of terrible radioactive contamination. There is a whole lake in Russia that contains high levels of radioactive materials. Maybe some effort will be made to safely store some of these dangerous materials for millennia, but they will be few and far between.
      If there is a collapse of our civilization because of resources exhaustion, greedy ruling elites and/or climate change, we will most likely be left with a global landscape scattered with dangerous zones where death and illness would find those who strayed into them. If the human race endures through the millennia, perhaps there will be legends of cursed lands to avoid. Maybe future civilizations will add their warning to avoid these places and they will be famous and well-known. Twisted and diseased plants and animals may also provide a warning to avoid these cursed lands. As with many problems that face us, only time will tell.
      And, finally, it may be that those who follow us will learn to curse their ancestors who tried to gain the power of the gods and failed miserably, leaving the world with a deadly legacy.

       Another idea for a warning system is to create a series of cartoon panels that show someone getting near the nuclear waste and then dying. However, it has the same problem as the pictogram with the possibility of being misunderstood. In addition, there is a problem with reading the panels in the proper order. There are four possible ways to read a set of panels; Left to right, right to left, top to bottom and bottom to top. Blanquer still believes that pictograms or icons have the best chance of survival.
      Blanquer’s doctoral thesis involved the creation of a system based on icons which indicated a physical action. His purpose is to develop a “a system that I can then make more complex in order to have people understand what I want them to understand; simply put, that there is radioactive waste under them.”
        French artist Bruno Grasser is second laureate of a prize on memory launched in 2016 by ANDR. His idea was to transmit knowledge of nuclear waste to the future by using etching. He would have a container filled with twenty-five hundred tiny cubes. Each forty years, the container would be passed to a new custodian and a mark would be scratched on the outside of the container. If each mark represents forty years, then when there are twenty-five hundred marks of the outside of the container, it would mean that a hundred thousand years had passed and the waste was safe. There are serious problems with this process. What if the custodian was killed or the container was lost or destroy? What if the meaning of the container vanished with time and became unconnected to a nuclear waste cache?
       So how could the human race pass some sort of indication of danger if the knowledge of nuclear materials and their dangers were lost. The research group created by the U.S. DoE described a number of different kinds of monuments that could serve as a signal of danger while surviving the centuries and millennia. Some of their ideas included a field of sharp spikes, threatening statues of things like lightning bolts or huge blocks of granite in a grid.
       Thirty years later and without any acknowledgment of the previous work, the Les Nouveaux Voisins, a pair of French architects, received the ANDRA 2016 first prize for their suggestions for something like Stonehenge, the ancient monument in southern England. They called for the placement of eighty one-hundred foot tall concrete columns above a nuclear waste storage repository. Oak trees would be planted on the top of these pillars which would sink into the ground over time. When the oak trees reached the ground, the nuclear waste would be safe. I would be worried that the mechanism that lowered the trees would not last long enough to lower the columns to ground level. The oak trees might be cut down. The meaning of the whole installation could fade with time.
