I think you would have to change the whole gov't! There is too much money involved for the big corporations. We are a 'sheep' society and are content to be herded by whatever the TV tells us. I feel overwhelmed by the whole thing,and so I just surround myself with people who do care and try to set a good example(remember the "vespa"? :) and talk to everyone about raising the general frame of consciousness. Having said that, I would love to be involved in a group that does something more.
