The natural environmental(ecosystem services)form the basis for human health and life. At present, however, large numbers of organisms are already becoming extinct due to the destruction of nature. In 1992, a group of the world's top scientists warmed humanity about the dangers to life and the global environment. Despite this, the situation continues to worsen and it is said that it will soon become difficult to change our course. Human activities(occupation)continue to cause the destruction of the natural world. Occupational science and occupa- tional therapy take occupation as their specialisation. They are professions which use individual activities(occu- pations)to promote occupational transformation. In this paper, I would like to suggest a practical route by which occupational science and occupational therapy can think about what they can do to build a sustainable society and humanity can overcome the planetary-scale crisis which deeply impacts human health and welfare.
