What is perpetuity? Why perpetuate? What is its relevance to us, the community, and the industry? This class will explore our relationship with sustainability from an economic and social point of view. After understanding the sustainable structure, focus on the industry, especially the agricultural level. In addition, in the course of this semester, we will invite Mr. Chen Jiantai to share with us the concepts and practices of Permaculture and CSA (Community Supported Agriculture) in permaculture. Gain theoretical and practical experience in permaculture.
