Following this experiment, Lin carefully observed the orchard environment and discovered that the original ecological chain of the mountain slopes on which the mango trees were planted had been all but destroyed owing to the fruit farmers 'major development of the area, by the use of fertilizer and ground clearing and the massive spraying of pesticides to prevent anthracnose. Naturally, these pesticides also killed off insects that played a role in pollination.
之後林宗賢仔細觀察果園環境，發現芒果所在的山坡地，因為果農大量開發，施肥除草，又為了預防炭疽病大量噴灑農藥，已將原有的生態鏈破壞殆盡，這其中當然包括各種授粉昆蟲。
