The 6 R’s are an important checklist. They are used by designers to reduce the environmental impact of products. They can also be used to evaluate the environmental impact of other products.
Respect – In order to understand what it means to be a part of the solution, you have to begin with respect. Respect for all things: people, animals, bugs, birds, fish, snakes, rivers, lakes, oceans, trees, mountains, valleys and so on.
Rethink — Everything on Earth is connected, and every decision you make has an impact. So rethink the things you bring with you and how you plan. THINK before you buy: "Where was this grown/made/manufactured? How far did it travel to get to the store?
Reduce — Reduce the amount of junk you send to the landfill. Are you a good consumer or a good conservationist? Do you really need all the stuff you think you need? Combine trips to reduce driving emissions and save money too.
Reuse — Before you throw anything away or into a recycle bin, ask yourself "Can I use this again? For something else perhaps?" Those plastic tubs with lids that so many products are sold in work great for storing leftovers or for arts and crafts projects.
Recycle — If you simply can’t find a new use, recycle everything possible. This can be a lot more than just throwing your cans in a bin. When you go to the salvage yard and buy a part for your car you are recycling. You're making use of existing items so raw materials won't have to be used to make more.
Restore — Always "pay it forward" and do your part. Try to make every place you visit a little bit nicer when you leave than when you got there.

RFID is similar to barcoding in that data from a tag or label are captured by a device that stores the data in a database. RFID, however, has several advantages over systems
