How are you doing your bit? Are you considering a change?

Ethical waste collection: Packaging of food- the waste and environmental damage in using food packaged in rigid plastic or tin and not recycling it for example.
Buying clothing ethically: Which, if any stores use manufacturing processes which do not take advantage of extremely low paid/slave labour?
Where do you shop? :)

What else should I be thinking about? What steps have you taken or are considering? All helpful replies appreciated.
