My sentence is...

"She lived a simple and ethical life".

I'm not sure I'm practicing  now, but I'm trying.

 First, about "simple". I am interested in ecology. I believe "to be simple" leads to ecology movement. I'd like to stop mass-produce and mass-consume and keep my suroundings simple. In addition, I would like to value "simple" feelings. For example, I smile heartily when I am happy, and I want to cry when I am sad.

 Second, abot "ethical". I am in the fair trade club because I believe that fair trade is  a "ethical" trade. And fair trade industry is closely related to organic fashion and food. They are produced with care about our health and safety.I think they are also "ethical". I want to live with these ethical products.

 Finally, I hope to be "simple" and "ethical" to people. It means "to be honest" to people.
