“Human-centered design” and “design thinking” are two approaches that have found their place within many companies and academic establishments because of their approach oriented towards reliable and viable solutions. Two strategic methodologies that put the user at the center of the design and development process of a product, a service or an entire business strategy. The importance of this approach continues to grow over the years, by placing the individual at the heart of its strategy. The concern is that although efforts have been made, the problem of waste, for example, persists largely due to the state of mind of human beings. Today, the problem is human behavior. We tend to put human at the center of everything, when in reality he was an integral part of the whole. The idea that humans are often seen as the focal point of design thinking when they can also be the root of the problem. What if we are on the wrong track in thinking about our ecological problems? The question we ask ourselves is why not change our mindset, and reconsider our role as human beings, ask questions and conceptualize solutions focused on social and environmental sustainability and know how we can move Design user-centered to a planet-centered design. Our article aims to raise the importance of taking into account the impact of our actions on the environment and recognizing our interdependence with other forms of life and the planet's ecosystems to create more effective solutions that preserve the planet and influences our behavior and our way of thinking.
