We can't shop our way out of ecological catastrophe (or spiritual emptiness).
The green revolution is not just for the middle class who can afford to pay extra for trendy fair-trade organic recycled chic. The middle class habit of buying far too much stuff is the problem, it can't be the solution.
The solution is to buy less stuff. Just buy less. It's not expensive. It's not hard. It's not rocket science.
Stuff. You don't need it.
