Excess packaging

It seems like many things I buy come in boxes that have bags and bags in them along with manuals, CDs, etc. I usually keep boxes and packaging for stuff I buy for 6 months to a year depending on what it is in case I have to return it or have it repaired under warranty. Yesterday, as I periodically do, I tossed a bunch of packaging that I no longer needed. As I was going through it, I realized that there is a lot that isn't needed. First off, blister packs are just awful to recycle as you really can't; cardboard boxes are much easier to recycle. However, marketers like people being able to see the contents. Second, I find the documentation in plastic bags. Is it really needed when there is scant documentation anyway? Then there is the CD. Is it really needed? Most times I download newer versions anyway. For those that can't download, how about a number they call to request the CD; these days there can't be that many people with that problem. In my process of tossing stuff, I separate out the paper/cardboard and plastic stuff. I recycle the paper/cardboard. How many people really do that? If the packaging were reduced and people were as conscientious as I, we could have a huge reduction in the amount of waste we send to the landfill.
