First, politics affects everyone and should be everyones business. It can throw us into faschism or worse if we all stay asleep.
Second, global warming may be complete nonsense or not, but I do know that fear of doing the right thing is crippling humanity. Right now I could be driving an electric car with zero toxic fumes and getting 60 miles a dollar, but instead I have to put up with a stinky  piston powered car and getting 8 miles a dollar.  Is that insane or not?   Humanity will crumble unless our leaders STOP BEING AFRAID OF DOING THE RIGHT THING.  NO MATTER WHAT THE COST,  DOING THE RIGHT THING ALWAYS LEADS TO SOMETHING BETTER.
