Raising the individuals’ awareness of the environmental problems, improving environmental sensitivity will make great contributions to the creation of sustainable environment (Hsu, 2004); hence, in line with the pre-service science teachers mostly acquire information about environmental problems from internet, radio and television, newspapers and magazines, people in the close circle, media should reserve more place and time for environmental programs, and the results of the environmental-friendly activities and campaigns should be broadcast so that the environmental awareness and sensitivity of the public can be fostered. And when the fact that people in the close circle is important about acquiring information is considered, people must have correct information and behavior. When the fact that the participant aren’t aware of the most important environmental problems too is considered, before closed environment is described and organized trip and discussed about it. And “from near to far” principle is applied.
