but there are lots of us, and growing every day!
talking to other like minded people helps loads. i have been much more cheerful since i started chatting on a few green forums e.g.
http://greenhome.huddler.com/forum/
taking local action; i have just joined the 'greening' campaign,

which hopefully will eventually link our villages and market town to the transition town movement

and getting outside. you can do a lot more than you think, but even growing a bit of salad gladdens the heart out of all proportion to the material benefit.
feel free to email me if you want to chat.
