The Climate change discussion surrounds us. This is true whether you believe the Climate is changing or not. The discussion envelopes whether we believe that Climate Change is the result of human activity or natural climate cycles. Similarly the discussion of what to do with our fossil fuel deposits is unavoidable, regardless of your attitude toward fossil fuel use. These two discussions dominate. It seems at times there is not enough oxygen left for other discussions, yet there are other resource issues we need to talk about if we wish to live responsibly and sustainably.
