Space is, of course, hard to come by in a country as small and as dense as Taiwan, so Tsay is of the opinion that farmers should decrease the use of pesticides and chemical fertilizers incrementally, one year at a time, to create a model of safe farming that protects both the environment and farmers 'livelihoods.
但台灣地狹人稠，廣大隔離田區難以取得，因此蔡東纂認為，最好的解決之道是教所有農民階段性、逐年地減少農藥和肥料的施用，從「安全農業」做起，才能兼顧生態與生計。
