The relationship between information technology and the environment is sort of mixed. In some ways, IT is good for the environment, but in other ways it is bad.
Bad: The main problem with IT is the fact that, as we get more and more IT, the demand for electricity rises (as more people want to use electronics in more ways). This, of course, means more fossil fuels will be burned to make the electricity. In addition, some compnents of electrical devices are very harmful to the environment if not properly disposed of.
Good: Ideally, IT can be used to help reduce stress on the environment. A good example of this is the "smart grids" that are under development. These would, it is hoped, help us use electricity much more efficiently, thus reducing the demand for electricity and the amount of resources used to produce that electricity.
I hope this is the sort of thing you meant by your question.
Information technology is a very powerful tool available to us today to improve performance in any endeavour of human activity. It can be used to achieve any given objective of human endeavour more effectively and efficiently. Protecting and improving environment is one of the many ares in which information technology can contribute a lot. The relationship of information technology with environment is same as that with any other organized activity.
Information technology can contribute to environment related activities at several levels. For example it can create awareness among consumers so that they choose environmental friendly products and methods. It can help businesses and other organizations to adopt environmental friendly practices. Also it can help to plan, monitor and control environmental programs at national and international levels.
Information technology helps us understand more about the environment we live in, but at the same time, can destroy the environment we live in.
