| Summary: | 碩士 === 臺灣大學 === 資訊管理學研究所 === 98 === Recently, the idea of environmental protection attracts everyone''s attention. However, few people notice that there also should be environmental protection in the virtual world.
Users use the resources which provide by the website holder in the virtual world. For users, those resources are free, so most of users upload contents unbridledly, and let junk mails occupy the mailbox. Nevertheless, it actually uses a lot of physical resources to provide the information storage and information transfer.
In this thesis, we remind the idea that there also should be environmental protection in the virtual world. In the researches presented before, digital universe is exploding. Moreover, the rate of information growth exceeds the storage available. For providing those storage spaces, companies use many resources, especially the consumption of non-renewable resources for providing electricity. It also resulted in serious environmental pollutions.
And then, we prove it by conducting the research. We use content analysis and take Flickr as an example for analyzing user-generated contents (UGC). There are many low-quality UGC in the virtual world. Junk mail is another problem in the virtual world. We interview with e-mail users. According to the studies, the average rate of junk mail in one person''s mailbox is 80%. Those contents waste plenty of internet resources and physical resources, and result in unnecessary environmental pollution.
In the end of this thesis, in order to reduce the information garbage, we suggest that we solve this problem from three ways which are user, website holder, and government. Everyone could delete the junk mail frequently, and filter the contents before uploading. Therefore, it could not only save the network space, but also reduce the resources consumption.
