As much as I want to disagree with you, I too have this bleak feeling of inevitable doom. As individuals there is nothing we can do, all the personal changes are dwarfed by the overwhelming magnitude of the problems ahead. In my younger years I would have thought that while the problems seem insurmountable, we as global society will find a solution. The older I get I am convinced that there is almost no political solution that won't be opposed by either big money or irrational nationalism blocking any kind of global solution.
