The carbon dioxide concentration has risen for numerous reasons, including the destruction of forests. The fewer trees and plants the are, the more carbon dioxide is the environment.
Carbon dioxide
Carbon dioxide (CO2) has increased significantly in the atmosphere since the beginning of the industrial revolution due to human activities such as burning fossil fuels and deforestation. This increase in CO2 concentration is a major contributor to global warming and climate change.
If the supply of carbon dioxide is reduced, the concentration of RuBP (ribulose-1,5-bisphosphate) will increase as it accumulates without being converted into GP (glycerate-3-phosphate). On the other hand, the concentration of GP will decrease since there will be fewer reactants available for its formation in the Calvin cycle.
The carbon content of the Earth's atmosphere has been increasing, particularly in the form of carbon dioxide (CO2) but also in the form of methane (CH4) which will eventually burn and become more carbon dioxide. And, the carbon content of the ocean is also increasing since carbon dioxide has been dissolving in the ocean.
The level of carbon dioxide in the atmosphere has increased significantly over the past century due to human activities such as burning fossil fuels and deforestation. This increase in carbon dioxide is a major contributor to global warming and climate change.
Carbon dioxide
Carbon dioxide is produced as a waste product of cellular metabolism in the body. It is transported to the lungs by the blood where it diffuses from the bloodstream into the lungs to be exhaled out of the body. This process helps maintain the balance of carbon dioxide levels in the body.
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.

Carbon dioxide (CO2) has increased significantly in the atmosphere since the beginning of the industrial revolution due to human activities such as burning fossil fuels and deforestation. This increase in CO2 concentration is a major contributor to global warming and climate change.
No, the amount of carbon dioxide in the atmosphere is 0.04% or 400 ppm (parts per million). This has risen since the Industrial Revolution from 280 ppm, when we began burning fossil fuels (coal, oil and natural gas).
The concentration of carbon dioxide in the air would increase if large trees were cut down. Trees help to absorb carbon dioxide during photosynthesis, so removing them would result in less carbon dioxide being removed from the atmosphere.
If the supply of carbon dioxide is reduced, the concentration of RuBP (ribulose-1,5-bisphosphate) will increase as it accumulates without being converted into GP (glycerate-3-phosphate). On the other hand, the concentration of GP will decrease since there will be fewer reactants available for its formation in the Calvin cycle.
Do you mean why does carbon dioxide diffuse out of the cells into the bloodstream? Diffusion is the movement of particles from a region of high concentration to a region of low concentration. Carbon dioxide is present in your body cells at a high concentration because the cells are making it. The process which makes carbon dioxide in cells is respiration. This is the release of energy from food. Carbon dioxide is a waste product of respiration. The carbon dioxide molecules diffuse into the blood because there is a lower concentration in the than in the cells. This is because the blood is always moving, so the carbon dioxide is carried away and does not build up. The difference in concentration between the cells and the blood keeps carbon dioxide diffusing in the correct direction.

The amount of carbon dioxide in the air in London is the same as all around the world, that is, 0.04%, or 400 ppm (parts per million) (in 2013). This has risen from 280 ppm in the past 200 years,since we started burning fossil fuels (coal, oil and natural gas).
Ofcource you need carbon dioxide! Weather we like it or not, we produce it, since when we breathe, we take in oxygen, but when we breathe out, we take ou Carbon Dioxide!
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.
