Everyone thinks they understand it, but if you went a step further and asked them why wild animals, which don't seem to have any connection with our daily lives, should be protected, there are probably very few who could give a cogent reply. And without a certain degree of understanding of ecology, it's very hard for people to achieve the ideals of environmental protection.
以看似人人能懂的生態保育為例，若進一步問為何要保護看來和我們生活不相關的野生動物？能夠完整回答的人恐怕寥寥無幾；而對環境缺乏某一程度的認知，人們也就很難去實踐保育的理想。
