We've been staying with a Thai family in Chiang mai for a week now. And I have the feeling that I often do, that I live inside a bit of a bubble when it comes to all things ethical and environmentally conscious. Just how long have the alleyways of the markets here been filled with so much plastic crap? And the roads filled with such big four wheel drives? An endless sea of nothing useful. Makes me feel deeply sorrowful for the challenge we all face. Inside I am a mixture of determination, and hopelessness.
