How is carbon dioxide harmful?

Answer 1

People and all animals breathe in oxygen and breathe out carbon dioxide. Their bodies are designed to breathe at a certain rate in order to eliminate carbon dioxide. If they are in an area high in carbon dioxide, they will breathe at an extremely rapid rate to get rid of the excess carbon dioxide even though there is enough oxygen.

Many scientists think the high level of carbon dioxide is the major cause of the ocean becoming more acidic. Carbon dioxide becomes a weak acid when mixed with water. The western world emits a tremendous amount of carbon dioxide.

Other scientists think the major cause of oceanic acidity is the tremendous amount of sulfuric acid thrown into the atmosphere by the factories of India and China. Sulfuric acid is a powerful acid.

Probably both contribute and with the tremendous amount of sewage and fertilizer poured into the ocean are causing ocean acidity resulting in the death of many coral reefs and before long will cause the decline of the shell fish industry. Your grandchildren will ask you, "What were oysters?"

Answer 2

Carbon dioxide makes it so that the heat that shines onto the Earth from the Sun cannot bounce back out, and traps it on the Earth's surface, much like the clear walls of a greenhouse trap the warmth and sun inside the building.

2nd Answer:

To actually answer your question . . . CO2 is not harmful to the atmosphere. In fact, without CO2, nearly every plant would die, cutting off our supply of oxygen. Without CO2 and other, more prevalent greenhouse gases, our world would be one giant iceball.

Answer 3

Excess Carbon dioxide Respiratory acidosis is a medical emergency in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally calledacidosis).

Carbon dioxide is produced continuously as the body's cells respire, and this CO2 will accumulate rapidly if the lungs do not adequately expel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased PaCO2 (a condition called hypercapnia). The increase in PaCO2 in turn decreases the HCO3−/PaCO2 ratio and decreases pH.

CO2 in general is not considered harmful unless allowed to concentrate in a confined place for example and displaces O2.

CO2 is classed as an asphyxiant gas

Answer 4

In the Atmosphere, it prevents the re-radiation of Incident Solar Radiation back into outer space; while in the Oceans, it increases their level of Acidity [with generally lethal consequences].

Answer 5

carbon dioxide is a Green house gas which causes global warming.

Answer 6

if you breath in a large amount it can kill you.

Answer 7

its not poinus because carbon dioxide is what we cant breathe in
