Global warming alarmists say the U. S. is the second biggest polluter in the world, next to China, yet the metric for that comparison is CO2, what we and the animals exhale as well is belched from volcanoes and course is emitted as a byproduct of fossil fuel burning, so Trump should confirm that he believes “climate change” is a hoax by saying bad breath is pollution while the CO2 coming out with it is not, the “bad breath” treatable, the CO2 what plants synthesize to grow!
