What can I do to be more sustainable?

Answer: 

Lead by example! Share literature, documentaries and interesting websites with others! Look into using public transport, alternative fuel types (as thePOOSH.org did on our EU Veggie Promo Tour), ride shares and possible hitching. Be available to talk! Communication, especially at meal times, can be one of the best forms of informal learning! You can even find a group that is talking about this or start one of your own.
