Yes, the disappearance of our beloved chocolate is foreseen for the near future. This is based on the current decline in cocoa production in West Africa, due to the spreading of viruses affecting the trees; hence it is believed that chocolate will not be purchasable by the masses. It will most probably be renamed the "brown gold".
If the current situation continues, then chocolate will have the same price as the caviare. Also this will be amplified by the fact that the farmers are paid very little, which does not give them an incentive to continue the time-consuming cultivation of cocoa, especially with the increase of tree viruses. Lets hope that a rapid and positive solution will be given to this issue.
