Environmental threats from IT Companies

I totally forgot about Blog Action day, a day when thousands of bloggers around the world write about same topic, environment. Here are few threats made to environment from IT Industry:

1. E-waste: Companies disposing unwanted computers & other peripherals which are not bio degradable.
2. Using glasses for buildings: Many IT companies uses glasses for their buildings to make it good looking. But this causes increase in temperature surround & inside building. Hence air conditioners consumes lot of electricity. Another disadvantage is Birds often dashes these glasses because of its reflectiveness.
3. Ups Batteries: All IT companies uses huge UPSs to prevent data loss due to power cut. These UPSs uses huge batteries which may be recycled. I know a company which buys these batteries to recycle. You can contact me for more on this.
