Time

I'm having quite a few deep thoughts today.  Here is just one more before I take Lupine to the eye doctor.  Why is it so difficult for humans to think about (see) time scales other than their own?  Anything that takes more than 100 years to happen seems way too long for anyone to comprehend.  Geologic time?  Evolution?  The creation of mountains and floodplains?  Ecological processes?  Long term economic theory?  Nope, we just can't get our big brains around it.  Someone, please, just tell me this.  Why are there no economists out there jumping up and down shouting about the long term consequences of a fossil fuel economy that is based (70% or more) on personal consumption by its citizens?  Myopia.
