Is carbon dioxide harmful

Answer 1

Depending upon the circumstance, carbon dioxide can be helpful or harmful. Plants inhale carbon dioxide and exhale oxygen. So, in this instance, carbon dioxide is necessary for the health of plants.

Carbon dioxide is produced as a byproduct of respiration by most animal on earth, such as human beings. We inhale oxygen, which is exchanged in the lungs for carbon dioxide to be exhaled as waste. Inhaling large amounts of carbon dioxide can lead to asphyxia (or asphyxiation), insufficient oxygen in the blood stream... which can lead to death.

Answer 2

Uhh... yeah it stops oxygen getting to the blood (simply because if your lungs are more full of CO2 then they are less likely to be full of Oxygen) nowhere near as lethal as CO (Carbon Monoxide) mainly because CO2 has a distinctive smell and can be smoky, CO is an odorless, colourless gas that is attracted to the haemoglobin in your red blood cells more than oxygen, depraving your muscles and organs of oxygen, effectively suffocating you, can be caused by incomplete combustion in faulty boilers, signs of this would be a yellow smoky flame in your boiler rather than a clean blue flame, breathing in Carbon Monoxide would make you dizzy and nauseous, the best solution is to go outside and then rush back inside when you are feeling fine, turn off your boiler and then get it serviced.

Basically, yes it is.

Answer 3

Carbon dioxide is heavier than air and is odorless. It can cause asphyxiation in high concentrations simply by displacing breathable oxygen. Breathing in high levels can also increase blood acidity with adverse affects.

Solid CO2 ,dry ice, is dangerous to handle as it causes skin damage.

Answer 4

CO2 is a naturally occurring waste product of animals. However it is harmful if encountered in too great concentrations, because then it displaces oxygen and there is not enough to continue living.of coure it is because it is literally poisen

Answer 5

Without the heat- blanketing effect of gases like carbon dioxide and methane (water vapour is also a greenhouse gas) , the earth would be much colder. Frozen, in fact. The levels have been quite stable for the last few million years, when higher life forms such as mammals have evolved. These lifeforms are the most vunerable to changes in the environment, and raising the average global temperature by only a few degrees is a threat to life. It's both useful, and harmful in excess .

Answer 6

Carbon dioxide is a naturally occurring gas that is essential for life on Earth. However, in high concentrations, such as those found in closed spaces, it can be harmful to humans by causing difficulty breathing and dizziness. Additionally, carbon dioxide is a greenhouse gas that contributes to global warming when present in excess in the atmosphere.

Answer 7

Both CO2 (carbon dioxide) and CO (carbon monoxide) are toxic. However CO is more toxic.
