we just work in terms of improvements ... changing our diet and lifestyle one bit at a time, and making sure we (where we can within the time and finances available) support brands who are ethical and encourage fair trade products.

are we doing everything we aspire to? no. but are we doing a lot better than we were 2 years ago? yes.

We are much the same, I believe you can only do what you can do & then more when possible. It's much the same as buying all Chemical free, I've slowly got all BPA free plates, bowls, cups for the kids and we use Chemical free washing powder etc. But sometimes when the budget simply can't support what we usually have or would like to get we either first go without if we can, or deal with what we have to for whatever amount of time. I at least know I am doing something, however small it is a start.
