The half of human wealth stems from natural capital, which we are depleting with our current economic model. Economic activity of human beings consumes more biomass than the Earth can produce on a sustainable basis. While our current model, “brown economy” is causing negative impacts on the environment, green economy decouples resource use and environmental impacts from economic growth decreasing the harmful effects of economic activities and aiming at sustainability over the long haul. Biomimicry is an innovation method seeking sustainable solutions for problems we humans face by imitating nature’s patterns and strategies that have formed during thousands of centuries. The method seeks to create environmentally friendly products, processes, and policies that are sustainable in the long run. This said, biomimicry is a method to consider in greening economic activities. Biomimicry is usually approached from technological and design point of view. This book highlights the connections between green economy and biomimicry, and includes an overview of strength and weaknesses of the method.
