Spaghetti Shiva: "Wasting" on the Internet

The concept of "wasting" changes on the internet. Unlike in the traditional paper world, you have technically unlimited space to write and store data. Using sites like Yahoo mail etc. you don't need to delete any message you have sent/received. In this case, ethics doesn't figure at all. When you waste paper or food, one is culturally made to think that "wasting is wrong." In the case of the internet you don't have anyone saying, that there are people who are less fortunate than you, or that using too much of Yahoo's server space is selfish and wrong.
