My thing is sustainability. One problem is that standard economics strongly discount future costs. The argument is basically that growth will give future generations the ability to solve any problems we cause. Ethically a dubious position to take.
However, there are glimmers of hope, some economists are beginning to question this assumption. New Scientist covers the details.
On a personal level, I think it is important to have a relationship with the land. We are individuals in communities rooted in a place. In my case the lower North Island of New Zealand. Part of my relationship with the land is responding to the beauty around me. The drawing is a quick sketch of a sunlit hill one morning.
