That's an interesting point, @anotherjoe! It's definitely interesting to see where people draw the lines for "good" and "bad", and potentially more interesting to see what escapes many people's awareness completely. As you point out, who considers the chemicals that go into treating wood? For another example, does anyone consider how far their organic produce had to travel to get to the store they're buying it from, and all the petroleum that goes into that, and where all the taxes go that are paid out at every step of the production process? Does anyone consider the amount of death and destruction that goes into producing toilet paper? There are many layers to what makes an option truly sustainable, and there is much opportunity for people to go deeper. There are so many ways to build a better world!!
