Here are the microorganisms reviled by the social imaginary, but essential in the functioning of the ecosystem. Through an invitation to play and in turn to discover the importance of these beings imperceptible to the naked eye. The work seeks to inspire in the youngest a healthy rebellion to defend nature. In the painting, each one appears with different characteristics and expressions, representing the richness of diversity. Invisible and tiny, microbes are everywhere and represent the oldest form of life. Some play essential roles, for example, in digestion, the breakdown of garbage or the growth of plants, while others are harmful, known as germs or viruses. One of the premises of this work is to find the vital balance of hygiene and the need to connect healthily with nature, the other one is to accept ourselves as we are, with our emotions and without stigmatizing.
