Art and Education

I am currently aware of the power of Art to educate , communicate and fight for a course.
Right now I am focusing on the environment, and the education art can provide to tell us about different environments. The Murray Darling River Basin , The Upper Florentine Forest in Tasmania, and locally Cabbage Tree Bay, Manly.
Just as I realise the potential art has to connect through forests and government, I am aware of the possiblities of connecting artists around the globe.
Just as I give voice to the next tree lost or endangered species I am suddenly made aware of the plight of a race, a race of people that are being supressed and locked into their own country. I speak of Tibet. In some ways it seems easier to save a tree, stand in front of it....but how do we save people?
