We began our mangrove planting activities in 1999 based on the concept of “insuring the earth’s future,” and have continued them without interruption for the last ten years. We realize, however, that much still remains to be done. Even the term “ecological” has lost some of its value as a result of popularization and overuse, but we nevertheless wish to declare to the people of the world that our project is of long-lasting ecological significance and that we shall continue our efforts for 100 years.
