I drove 1800 miles in a Hydrogen Car

No, you don't have to worry constantly about your CO2 "emissions".  540 million years ago (in the Cambrian explosion of life), atmospheric CO2 levels were some 15x higher than today.  The planet never burned to a crisp allowing us to evolve and be defrauded by this fraudulent "green" industry.  There is no proven man-made climate catastrophe.  Instead of simply regurgitating media lies, check it or yourselves.
