How about something as simple as starting at home by recycling or what is more, by motivating others to do it as well. Environmental education is a must in order to generate consciousness in the issue. Once they know, they can choose wether to deal with it or not, but at least they will have been warned about the consequences of not doing so.
For my life style 0.4 planets are required and I use 0.8 global hectares of productive land. I don't know how to reduce it further. The greatest problem is that I travel 25 km or so in van to my university every day. I can't walk to it. I cannot recycle my glass as I don't know any such recycling centers in Pakistan.
