            Every day new innovations are created in order to preserve the planet like this micro house in Nantes. Its promoters intend to raise awareness about ecology and offer a habitat at a lower cost. Four friends from Nantes build the micro-house Les Albers: a tiny house full of sensors. Electricity production and consumption, such as available water, ambient humidity, or temperature, can be viewed live from a computer or phone. Even if the total autonomy is not yet reached (a cylinder of gas supplies the stove, hot water and gas stove), this tiny house aims to be as ecological as possible. Three solar panels provide electricity for lighting and the refrigerator, and the shower and sink are powered by rainwater.             To conclude, we must act quickly so the future generations can live in a \"healthy\" world. A Native American legend says, \"One day, there is a huge forest fire. terrified and aghast animals watch helplessly, disaster. Only the hummingbird is activated, going look for a few drops of water in his beak to throw them on the fire. After a while, the armadillo, annoyed by his useless movements, said to him: \"Colibri! You're not crazy ? You think it's with these drops of water that you will extinguish the fire? I know it, the hummingbird answers, but I'm doing my part. \"So if everyone tries to save the planet we will get there and we can raise our children in a beautiful world.
