Linux and Environment-Why Linux is Better?

• The freeware is easily downloadable from the internet and hence doesn't need be packed into boxes.Windows and Mac OS,on the other hand, are sold in boxes which requires massive amounts of paper and plastic to be manufactured. We all are aware how these products (paper and plastic)have negative impacts on the environment.
• Proprietary applications for Windows or Mac OS are also, most of the time, sold in local stores, in boxes, whereas one can download the vast majority of software for Linux from the Internet, for free (again, a whole lot of saved paper and plastic!).
• Linux may easily be run on even very old machines hence  they can be recycled for various purposes (storage, internet access, multimedia box, etc.) instead of being thrown out! On the other hand, other Operating Systems require much advanced machines. The requirements keep on increasing with time.
• Millions of CDs are pressed to hold Windows or Mac OS boxes and are sold to customers. Linux also needs to be burnt on a CD before installation (in most cases at least -- installation from the network or from a hard disk is also quite common). However, most people choose to burn it on a rewritable CD ("CD-RW"), which can be reused for other purposes after the installation is over (unlike proprietary operating systems, you don't need to keep the CD around after you've installed the software, you can always download it again later).
