It's a ridiculous statement. Not only does CO2 keep all plant life alive, it also creates an atmosphere that keeps the earth warm and habitable. Dude is an idiot.
This guy is an example of why the office of the president doesn’t need experieneed politicians as the CEO of the nation. They are complete idiots as to running an Executive Office. Biden is the worst possible candidate and now is President of the country because his entire career is as a politician that did nothing positive or independent. He occupied his time with lobbyist and party line manipulations. Kerry is just another example of a career politician. All jawboning and shooting from the hip. He isnt smart enough to know that his best posture is to say nothing.
I have heard too many times about Presidential candidates who have no experience in politics and shouldn’t be President. They are actually the best candidates if they come from executive positions such as business or State Governors. Regan and Trump are good examples. The more political experience the less competent politicians are people who should not fill cabinet and Agency appointments but that is what you get when a politician gets in office.
