First off, "Reduce"
Let's start with bulk buying. The while point of bulk is that you leave the store with the same containers you arrived with, no more, no less. Strictly speaking, it is "bulk" buying if you buy in quantity or appropriate amounts that you individually package, but for the purposes of eco-friendly lifestyles, "bulk" means that you bring your own containers and bags and actually use them.
"Reduce", of course, means not buying anything that you don't need. The operative word is "need". Of course I am not suggesting that all readers immediately switch to lives of asceticism, but how many pairs of shoes do you really need? Blouses? Computer toys? It is truly terrifying how many North Americans regard "shopping" as an acceptable social activity, practised every day or two. Apparently the average is 6 hours per week.
Now for "Reuse"
Keep using the old one. Make rags out of old cloths. Return items for reuse. Donate to various goodwill agencies - only what you no longer have a use for. If you are simply buying a new one for yourself,you have not done the planet any favours. Find new uses for "garbage". Borrow, or buy second-hand.
"Recycle" is next
Many environmentalists were initially opposed to recycling because they felt it would be seen as a panacea and people would forget about waste reduction. Sadly those fears are being realized.
Let's be clear about what recycling actually is. Recycling is when materials are reprocessed and manufactured into the same or similar products. [Most] plastics, for example, cannot actually be recycled. Plastics are subject to what is known as "downcycling". Downcycling is when the waste product is reprocessed and as a result becomes a lower grade of resource and comes back as a different product. Optimally plastic can make a maximum of four "cycles", although usually it is lucky if it makes one trip through the spiral. There is no question that it is a good thing that we are able to make shirts and other products out of plastic waste, but that in no way changes the fact that we still need a massive reduction in our waste, whether to the dump or the recycling plant.
