What's done is done, but those about to rectify past errors have no desire to commit errors of their own. In fact ecologists are themselves learning through the restoration process. It is not by money or the number of fish that the fruits of the project should be judged, but by the even more important function of environmental education.
往者已矣，希望未來錯誤不再重複，生態學界其實也在學習，因此不需要以金錢、魚的數量來衡量復育成果，過程附帶的環境教育功能其實更重要。
