Carbon dioxide is a naturally occurring compound in the atmosphere. Total amount has to be in the trillions of pounds.
There is a more in depth answer at the link below.
When a tree is removed, it can no longer remove any carbon dioxide from the atmosphere.
The amount of carbon dioxide being removed from the atmosphere. (These activities are cutting down and destroying forests.)
I think it is 0.1227 pounds but I have seen 0.1144 pounds used.
With the break up of the supercontinenent, Rodinia, there were of course many smaller continents which led to more rainfall and consequently less carbon dioxide in the atmosphere (since rain "washes" the carbon dioxide out of the atmosphere). As a result of less carbon dioxide in the atmosphere, temperatures dropped and ice began to form in polar regions.
The Earth's atmoshpere is a mixture of many gases, including nitrogen, oxygen, carbon dioxide, and hydrogen.
When a tree is removed, it can no longer remove any carbon dioxide from the atmosphere.
Nature produces the vast bulk of carbon dioxide in the atmosphere. Rotting trees, and dead matter produce over 90% of the current levels of carbon dioxide. Man produces between 3 and 6 percent of all CO2 annually.
the atmosphere is made of carbon dioxide and other gases e.g. oxygen and carbon dioxide
Carbon dioxide is released into the atmosphere from many sources including our breathing. This carbon dioxide is the pollution that causes global warming. Trees naturally absorb carbon dioxide to create energy and therefore stop it from being released into the atmosphere. This is why we need to conserve our forests.

Many things contribute to Carbon dioxide being released. Cars, animals, burning fossil fuels, etc.
