Bhutan, it is a small asian country that has a neutral carbon footprint and they are working on having a negative carbon footprint. Not only that, but they have a minster of happiness, this country cares more about being happy and not harming the environment. It is also a buddhist kingdom, so becoming a buddhist monk would also be easy.
i find this suggested location interesting. i don't know much about bhutan, but i do know a little about buddhism and the monks. i'm not sure if the simple life is for me, but i do find it appealing. i like that they are more in tune with each other and their environment than wealth and material possessions.
