I shop ethically, I drive a small 4-cyl car, live in a small house, use flouro lightbulbs (have done for years). I am a student, I have little income, I am a vegan. I buy local produce wherever possible, attempt to grow a few veggies, buy ethical, animal product-free, products and rarely buy new clothes until my old ones have worn out.
Some people might do the Green Thing cos they are well off, and want to give themselves a pat on the back (who cares, it's better they do that than not, especially if they insist on driving a Hummer around town). I don't. I think it's dangerous to generalise, as there can be a social backlash to choosing ethical habits if they are made out to be only an option for the wealthy.
Using bi-carb soda, vinegar and borax for cleaning is cheap, easy and ethical. Eating vegan is cheap and ethical, but does require some extra effort in preparation.
Then there's the plastic bag issue while out shopping. I use fabric bags, and simply plonk all my veggies onto the counter. I invested in Tupperware stay-fresh containers years ago, so all the veggies come home, get washed, chopped and put into those for storage in the fridge. If I get asked if i want plastic bags.. I just say "Heck no... Australians use 6 billion plastic bags a year. Can you believe it?? I don't want any part of that".
