Abstract: It is important to know and be interested in our familiar environments so as to identify environmental problems and take appropriate actions. In this article, I have introduced several examples of researches on the knowledge, consciousness and experience of familiar natural environments and crops. The survey of recreational activities with flowers and plants showed that people are less involved with plants in such activities. The survey on alien plants showed that many people are unable to identify alien plants. The survey on parent’s awareness and experience of vegetables showed that few would plant vegetables voluntarily, and parent’s experience and consciousness about vegetables may affect their children. With these results, I believe that nature experience activities require appropriate support from the adult, and it is necessary to increase the opportunities for adults to participation in the activities at home and in their communities.
