What are the disadvantages of carbon dioxide ?
Carbon dioxide harms
Increasing the percentage of carbon dioxide gas in the air causes suffocation of living organisms as well as global warming that threaten the existence of life on this planet , high concentration of carbon dioxide gas causes narcosis .
Carbon dioxide gas level increases to higher than 5 % in the room , this ratio is enough to kill the human being , carbon dioxide gas increases the cerebral blood flow and intracranial pressure .
Increasing the percentage of carbon dioxide gas in air causes melting the snow on the tops of mountains and the two poles causing the raise of the level of sea water , so some coastal towns will drown .
Burning of fossil fuels increases carbon dioxide gas emissions , and it causes a gap in the ozone layer which protects the Earth from harmful rays coming from the Sun , when the harmful rays enter the Earth’s atmosphere , it raises the temperature of the planet which is known as the green house effect .
Symptoms of carbon dioxide gas toxicity are high blood pressure , headache , flushed skin and twitching the muscles , and at higher levels , man can experience panic , hallucinations , vomited , irregular heartbeat and potentially unconsciousness or even death due to rising of carbon dioxide concentration in the blood and tissues .
Rising the levels of carbon dioxide gas stimulates sympathetic nervous system which may be dangerous in some patients already having systemic hypertension or myocardial ischaemia .
