I drove 1800 miles in a Hydrogen Car

Electric and Hydrogen cars both take more carbon and mining of rare materials (lithium for electric & hydrogen car batteries and platinum for hydrogen fuel cells) before the car dealer even gets the vehicle. 
My diesel car can travel 800km highway driving, whereas an electric car can only travel 150kms before charging is required. With fuel emissions regulators in heavy vehicles, I don't see any exhaust gases billowing in clouds of smog.
One question about carbon, when all the carbon is removed, where will all the plant life get their food?
