Global cooperation is essential. We have a responsibility to restore what we have polluted. For that, we have to return to living modestly rather than pursuing a materialistic way of living. As natural resources are limited, we have to establish social systems to reuse and recycle what we use. If waste is classified as it is collected, it can become a resource again rather than a pollutant.
Population is of vital importance.
Recognizing the importance of the environment, we have to educate and guide the next generation. In addition, if we can live sustainably, we can find the direction to go. We have to recognize that fossil energy will soon be exhausted, but we can rely on solar energy and still maintain a certain standard of living. In parallel with the house construction, we are designing a computer program to assist an architect to plan and design a nature-friendly and sustainable house. The program is based on the data at the site.
