Apparently (according to my mum) Nostradamus predicted all of this centuaries ago.
He reckoned there would be a time when money had no value - I think we're getting close to that one.
I don't know much about the man or his prophecies, but wonder if anyone else does and what they think ?
I don't believe your mum is that old!

I do believe, however, that the world will face a global crisis in the near future, and that it has already started.
The future will demand that many issues are addressed on a local scale, and that a return to simplistic living will be necessary to ensure the survival of some of the human race. There will have to be a return to home grown food as there will not be the wherewithall to import foods to the same extent as today.
Third world countries will be severely affected, with many millions of people dying as a result of global shortages of fuel, food, and the means to move stuff around the world.
The world of the future will be a very dangerous place to live owing to shortages of food and fuel causing civil unrest, particularly in the cities, and a breakdown of society as need cancels out any vestige of common decency and respect. People will be driven by need rather than greed, and that will cause many more problems than we have ever known.
Those members of society who are despised today for their hunting instincts and abilities, will be revered and appreciated once again as individuals who can help feed localised communties, as will those who have tended their little plots of soil for so many generations, growing enough to feed a few here and there. So many natural abilities have become forgotten or lost as the new world destroyed the old and its indigenous peoples, and their knowledge.
Those who have lost (or never had) such instincts/abilities will be the most dangerous people on the planet, as everyday necessary items of food and equipment become scarce.
The 'modern' countries of the world will face the worst kind of future as it is here that the populations have become so diverse that any common bond of culture is non existent, and communities lack the means of meaningful and prosperous cohesion.
Add to this the problems of apathy, drugs, greed, brutality, money (or lack of it), disease, war, global environmental change, and the general arrogance of the human race....................
Nostradamus probably did predict this many years ago, and he may, at that time, have been the only one who believed it. Now it seems inevitable.
Anyone with any sense can surely see that we are the victims of our own success as a species, and that we are, as a species, reacting in the only way we can to an environment which has been ruined by overpopulation and poisoning.............we are evolving in a downward trend.
