In this collection of cardboard environmental, Victor Solis gives voice to that part of it seems that man is no longer part; nature. Deforestation, irrational exploitation of environmental resources, pollution, ecosystem degradation, extinction of wildlife, green fashions, are key themes in the work of Solis, like his irreverent way of dealing with them. A book to confront us with ourselves, Cardboard lucid, naive and harmless in appearance, which make us laugh with the same coup with which we are questioning. The voice of nature, so distant from the man, a frightened voice, critical, unforgiving, but somehow, compassionate. The humor humanizes us, and it is this sense of the primordial human being calling the appeal of the artist, to put us with a smile in the mouth, in the center of reflection, the reflection on the future of our planet and our own existence.
