El cambio

The adventure of two polar bears, father and son, who go hunting and realize that they cannot return because the ice walkway has melted. The tender illustrations that narrate the anguish of the two bears, especially the smallest, alternate with much darker images about the environmental impact of factories, cattle farms or the felling of trees, especially in the Amazon. The ice returns and finally everything begins to change and father and son can return to the rest of the family because the ice covers the Pole again. It has been the actions of some children that have brought about that change that leads them to a happy ending.
