Peter Garret was a zealot for environmentalism, especially his stance against uranium mining.  However as he got older and more involved in politics he came understand some more of the complexity involved and changed his views.  Many of us start out passionate and sure of ourselves but we do need to eat humble pie sometimes and sit with paradox, complexity and nuance.   Building this chicken in my workshop is a good example, looks simple, but its actually a very sophisticated work of art!
